+Compiled-in Device Tree / Platform Data
+=======================================
+
+
+Introduction
+------------
+
+Device tree is the standard configuration method in U-Boot. It is used to
+define what devices are in the system and provide configuration information
+to these devices.
+
+The overhead of adding devicetree access to U-Boot is fairly modest,
+approximately 3KB on Thumb 2 (plus the size of the DT itself). This means
+that in most cases it is best to use devicetree for configuration.
+
+However there are some very constrained environments where U-Boot needs to
+work. These include SPL with severe memory limitations. For example, some
+SoCs require a 16KB SPL image which must include a full MMC stack. In this
+case the overhead of devicetree access may be too great.
+
+It is possible to create platform data manually by defining C structures
+for it, and reference that data in a `U_BOOT_DRVINFO()` declaration. This
+bypasses the use of devicetree completely, effectively creating a parallel
+configuration mechanism. But it is an available option for SPL.
+
+As an alternative, the 'of-platdata' feature is provided. This converts the
+devicetree contents into C code which can be compiled into the SPL binary.
+This saves the 3KB of code overhead and perhaps a few hundred more bytes due
+to more efficient storage of the data.
+
+
+How it works
+------------
+
+The feature is enabled by CONFIG OF_PLATDATA. This is only available in
+SPL/TPL and should be tested with:
+
+.. code-block:: c
+
+    #if CONFIG_IS_ENABLED(OF_PLATDATA)
+
+A tool called 'dtoc' converts a devicetree file either into a set of
+struct declarations, one for each compatible node, and a set of
+`U_BOOT_DRVINFO()` declarations along with the actual platform data for each
+device. As an example, consider this MMC node:
+
+.. code-block:: none
+
+    sdmmc: dwmmc@ff0c0000 {
+            compatible = "rockchip,rk3288-dw-mshc";
+            clock-freq-min-max = <400000 150000000>;
+            clocks = <&cru HCLK_SDMMC>, <&cru SCLK_SDMMC>,
+                     <&cru SCLK_SDMMC_DRV>, <&cru SCLK_SDMMC_SAMPLE>;
+            clock-names = "biu", "ciu", "ciu_drv", "ciu_sample";
+            fifo-depth = <0x100>;
+            interrupts = <GIC_SPI 32 IRQ_TYPE_LEVEL_HIGH>;
+            reg = <0xff0c0000 0x4000>;
+            bus-width = <4>;
+            cap-mmc-highspeed;
+            cap-sd-highspeed;
+            card-detect-delay = <200>;
+            disable-wp;
+            num-slots = <1>;
+            pinctrl-names = "default";
+            pinctrl-0 = <&sdmmc_clk>, <&sdmmc_cmd>, <&sdmmc_cd>, <&sdmmc_bus4>;
+                vmmc-supply = <&vcc_sd>;
+                status = "okay";
+                u-boot,dm-pre-reloc;
+        };
+
+
+Some of these properties are dropped by U-Boot under control of the
+CONFIG_OF_SPL_REMOVE_PROPS option. The rest are processed. This will produce
+the following C struct declaration:
+
+.. code-block:: c
+
+    struct dtd_rockchip_rk3288_dw_mshc {
+            fdt32_t         bus_width;
+            bool            cap_mmc_highspeed;
+            bool            cap_sd_highspeed;
+            fdt32_t         card_detect_delay;
+            fdt32_t         clock_freq_min_max[2];
+            struct phandle_1_arg clocks[4];
+            bool            disable_wp;
+            fdt32_t         fifo_depth;
+            fdt32_t         interrupts[3];
+            fdt32_t         num_slots;
+            fdt32_t         reg[2];
+            fdt32_t         vmmc_supply;
+    };
+
+and the following device declarations:
+
+.. code-block:: c
+
+    /* Node /clock-controller@ff760000 index 0 */
+    ...
+
+    /* Node /dwmmc@ff0c0000 index 2 */
+    static struct dtd_rockchip_rk3288_dw_mshc dtv_dwmmc_at_ff0c0000 = {
+            .fifo_depth             = 0x100,
+            .cap_sd_highspeed       = true,
+            .interrupts             = {0x0, 0x20, 0x4},
+            .clock_freq_min_max     = {0x61a80, 0x8f0d180},
+            .vmmc_supply            = 0xb,
+            .num_slots              = 0x1,
+            .clocks                 = {{0, 456},

+                                       {0, 114},
+                                       {0, 118}},

+            .bus_width              = 0x4,
+            .u_boot_dm_pre_reloc    = true,
+            .reg                    = {0xff0c0000, 0x4000},
+            .card_detect_delay      = 0xc8,
+    };
+
+    U_BOOT_DRVINFO(dwmmc_at_ff0c0000) = {
+            .name           = "rockchip_rk3288_dw_mshc",
+            .plat       = &dtv_dwmmc_at_ff0c0000,
+            .plat_size  = sizeof(dtv_dwmmc_at_ff0c0000),
+            .parent_idx     = -1,
+    };
+
+The device is then instantiated at run-time and the platform data can be
+accessed using:
+
+.. code-block:: c
+
+    struct udevice *dev;
+    struct dtd_rockchip_rk3288_dw_mshc *plat = dev_get_plat(dev);
+
+This avoids the code overhead of converting the devicetree data to
+platform data in the driver. The `of_to_plat()` method should
+therefore do nothing in such a driver.
+
+Note that for the platform data to be matched with a driver, the 'name'
+property of the `U_BOOT_DRVINFO()` declaration has to match a driver declared
+via `U_BOOT_DRIVER()`. This effectively means that a `U_BOOT_DRIVER()` with a
+'name' corresponding to the devicetree 'compatible' string (after converting
+it to a valid name for C) is needed, so a dedicated driver is required for
+each 'compatible' string.
+
+In order to make this a bit more flexible, the `DM_DRIVER_ALIAS()` macro can be
+used to declare an alias for a driver name, typically a 'compatible' string.
+This macro produces no code, but is used by dtoc tool. It must be located in the
+same file as its associated driver, ideally just after it.
+
+The parent_idx is the index of the parent `driver_info` structure within its
+linker list (instantiated by the `U_BOOT_DRVINFO()` macro). This is used to
+support `dev_get_parent()`.
+
+During the build process dtoc parses both `U_BOOT_DRIVER()` and
+`DM_DRIVER_ALIAS()` to build a list of valid driver names and driver aliases.
+If the 'compatible' string used for a device does not not match a valid driver
+name, it will be checked against the list of driver aliases in order to get the
+right driver name to use. If in this step there is no match found a warning is
+issued to avoid run-time failures.
+
+Where a node has multiple compatible strings, dtoc generates a `#define` to
+make them equivalent, e.g.:
+

+
+Converting of-platdata to a useful form
+---------------------------------------
+
+Of course it would be possible to use the of-platdata directly in your driver
+whenever configuration information is required. However this means that the
+driver will not be able to support devicetree, since the of-platdata
+structure is not available when devicetree is used. It would make no sense
+to use this structure if devicetree were available, since the structure has
+all the limitations metioned in caveats below.
+
+Therefore it is recommended that the of-platdata structure should be used
+only in the `probe()` method of your driver. It cannot be used in the
+`of_to_plat()` method since this is not called when platform data is
+already present.
+
+
+How to structure your driver
+----------------------------
+
+Drivers should always support devicetree as an option. The of-platdata
+feature is intended as a add-on to existing drivers.
+
+Your driver should convert the plat struct in its `probe()` method. The
+existing devicetree decoding logic should be kept in the
+`of_to_plat()` method and wrapped with `#if`.
+
+For example:
+
+.. code-block:: c
+
+    #include <dt-structs.h>
+
+    struct mmc_plat {
+    #if CONFIG_IS_ENABLED(OF_PLATDATA)
+            /* Put this first since driver model will copy the data here */
+            struct dtd_mmc dtplat;
+    #endif
+            /*
+             * Other fields can go here, to be filled in by decoding from
+             * the devicetree (or the C structures when of-platdata is used).
+             */
+            int fifo_depth;
+    };
+
+    static int mmc_of_to_plat(struct udevice *dev)
+    {
+    #if !CONFIG_IS_ENABLED(OF_PLATDATA)
+            /* Decode the devicetree data */
+            struct mmc_plat *plat = dev_get_plat(dev);
+            const void *blob = gd->fdt_blob;
+            int node = dev_of_offset(dev);
+
+            plat->fifo_depth = fdtdec_get_int(blob, node, "fifo-depth", 0);
+    #endif
+
+            return 0;
+    }
+
+    static int mmc_probe(struct udevice *dev)
+    {
+            struct mmc_plat *plat = dev_get_plat(dev);
+
+    #if CONFIG_IS_ENABLED(OF_PLATDATA)
+            /* Decode the of-platdata from the C structures */
+            struct dtd_mmc *dtplat = &plat->dtplat;
+
+            plat->fifo_depth = dtplat->fifo_depth;
+    #endif
+            /* Set up the device from the plat data */
+            writel(plat->fifo_depth, ...)
+    }
+
+    static const struct udevice_id mmc_ids[] = {
+            { .compatible = "vendor,mmc" },
+            { }
+    };
+
+    U_BOOT_DRIVER(mmc_drv) = {
+            .name           = "mmc_drv",
+            .id             = UCLASS_MMC,
+            .of_match       = mmc_ids,
+            .of_to_plat = mmc_of_to_plat,
+            .probe          = mmc_probe,
+            .priv_auto = sizeof(struct mmc_priv),
+            .plat_auto = sizeof(struct mmc_plat),
+    };
+
+    DM_DRIVER_ALIAS(mmc_drv, vendor_mmc) /* matches compatible string */
+
+Note that `struct mmc_plat` is defined in the C file, not in a header. This
+is to avoid needing to include dt-structs.h in a header file. The idea is to
+keep the use of each of-platdata struct to the smallest possible code area.
+There is just one driver C file for each struct, that can convert from the
+of-platdata struct to the standard one used by the driver.
+
+In the case where SPL_OF_PLATDATA is enabled, `plat_auto` is
+still used to allocate space for the platform data. This is different from
+the normal behaviour and is triggered by the use of of-platdata (strictly
+speaking it is a non-zero `plat_size` which triggers this).
+
+The of-platdata struct contents is copied from the C structure data to the
+start of the newly allocated area. In the case where devicetree is used,
+the platform data is allocated, and starts zeroed. In this case the
+`of_to_plat()` method should still set up the platform data (and the
+of-platdata struct will not be present).
+
+SPL must use either of-platdata or devicetree. Drivers cannot use both at
+the same time, but they must support devicetree. Supporting of-platdata is
+optional.
+
+The devicetree becomes inaccessible when CONFIG_SPL_OF_PLATDATA is enabled,
+since the devicetree access code is not compiled in. A corollary is that
+a board can only move to using of-platdata if all the drivers it uses support
+it. There would be little point in having some drivers require the device
+tree data, since then libfdt would still be needed for those drivers and
+there would be no code-size benefit.
+
+
+Build-time instantiation
+------------------------
+
+Even with of-platdata there is a fair amount of code required in driver model.
+It is possible to have U-Boot handle the instantiation of devices at build-time,
+so avoiding the need for the `device_bind()` code and some parts of
+`device_probe()`.
+
+The feature is enabled by CONFIG_OF_PLATDATA_INST.
+
+Here is an example device, as generated by dtoc::
+
+   /*
+    * Node /serial index 6
+    * driver sandbox_serial parent root_driver
+   */
+
+   #include <asm/serial.h>
+   struct sandbox_serial_plat __attribute__ ((section (".priv_data")))
+      _sandbox_serial_plat_serial = {
+      .dtplat = {
+         .sandbox_text_colour   = "cyan",
+      },
+   };
+   #include <asm/serial.h>
+   u8 _sandbox_serial_priv_serial[sizeof(struct sandbox_serial_priv)]
+      __attribute__ ((section (".priv_data")));
+   #include <serial.h>
+   u8 _sandbox_serial_uc_priv_serial[sizeof(struct serial_dev_priv)]
+      __attribute__ ((section (".priv_data")));
+
+   DM_DEVICE_INST(serial) = {
+      .driver     = DM_DRIVER_REF(sandbox_serial),
+      .name       = "sandbox_serial",
+      .plat_      = &_sandbox_serial_plat_serial,
+      .priv_      = _sandbox_serial_priv_serial,
+      .uclass     = DM_UCLASS_REF(serial),
+      .uclass_priv_ = _sandbox_serial_uc_priv_serial,
+      .uclass_node   = {
+         .prev = &DM_UCLASS_REF(serial)->dev_head,
+         .next = &DM_UCLASS_REF(serial)->dev_head,
+      },
+      .child_head   = {
+         .prev = &DM_DEVICE_REF(serial)->child_head,
+         .next = &DM_DEVICE_REF(serial)->child_head,
+      },
+      .sibling_node   = {
+         .prev = &DM_DEVICE_REF(i2c_at_0)->sibling_node,
+         .next = &DM_DEVICE_REF(spl_test)->sibling_node,
+      },
+      .seq_ = 0,
+   };
+
+Here is part of the driver, for reference::
+
+   static const struct udevice_id sandbox_serial_ids[] = {
+      { .compatible = "sandbox,serial" },
+      { }
+   };
+
+   U_BOOT_DRIVER(sandbox_serial) = {
+      .name   = "sandbox_serial",
+      .id   = UCLASS_SERIAL,
+      .of_match    = sandbox_serial_ids,
+      .of_to_plat  = sandbox_serial_of_to_plat,
+      .plat_auto   = sizeof(struct sandbox_serial_plat),
+      .priv_auto   = sizeof(struct sandbox_serial_priv),
+      .probe = sandbox_serial_probe,
+      .remove = sandbox_serial_remove,
+      .ops   = &sandbox_serial_ops,
+      .flags = DM_FLAG_PRE_RELOC,
+   };
+
+
+The `DM_DEVICE_INST()` macro declares a struct udevice so you can see that the
+members are from that struct. The private data is declared immediately above,
+as `_sandbox_serial_priv_serial`, so there is no need for run-time memory
+allocation. The #include lines are generated as well, since dtoc searches the
+U-Boot source code for the definition of `struct sandbox_serial_priv` and adds
+the relevant header so that the code will compile without errors.
+
+The `plat_` member is set to the dtv data which is declared immediately above
+the device. This is similar to how it would look without of-platdata-inst, but
+node that the `dtplat` member inside is part of the wider
+`_sandbox_serial_plat_serial` struct. This is because the driver declares its
+own platform data, and the part generated by dtoc can only be a portion of it.
+The `dtplat` part is always first in the struct. If the device has no
+`.plat_auto` field, then a simple dtv struct can be used as with this example::
+
+   static struct dtd_sandbox_clk dtv_clk_sbox = {
+      .assigned_clock_rates   = 0x141,
+      .assigned_clocks   = {0x7, 0x3},
+   };
+
+   #include <asm/clk.h>
+   u8 _sandbox_clk_priv_clk_sbox[sizeof(struct sandbox_clk_priv)]
+      __attribute__ ((section (".priv_data")));
+
+   DM_DEVICE_INST(clk_sbox) = {
+      .driver    = DM_DRIVER_REF(sandbox_clk),
+      .name      = "sandbox_clk",
+      .plat_     = &dtv_clk_sbox,
+
+Here is part of the driver, for reference::
+
+   static const struct udevice_id sandbox_clk_ids[] = {
+      { .compatible = "sandbox,clk" },
+      { }
+   };
+
+   U_BOOT_DRIVER(sandbox_clk) = {
+      .name       = "sandbox_clk",
+      .id         = UCLASS_CLK,
+      .of_match   = sandbox_clk_ids,
+      .ops        = &sandbox_clk_ops,
+      .probe      = sandbox_clk_probe,
+      .priv_auto  = sizeof(struct sandbox_clk_priv),
+   };
+
+
+You can see that `dtv_clk_sbox` just has the devicetree contents and there is
+no need for the `dtplat` separation, since the driver has no platform data of
+its own, besides that provided by the devicetree (i.e. no `.plat_auto` field).
+
+The doubly linked lists are handled by explicitly declaring the value of each
+node, as you can see with the `.prev` and `.next` values in the example above.
+Since dtoc knows the order of devices it can link them into the appropriate
+lists correctly.
+
+One of the features of driver model is the ability for a uclass to have a
+small amount of private data for each device in that uclass. This is used to
+provide a generic data structure that the uclass can use for all devices, thus
+allowing generic features to be implemented in common code. An example is I2C,
+which stores the bus speed there.
+
+Similarly, parent devices can have data associated with each of their children.
+This is used to provide information common to all children of a particular bus.
+For an I2C bus, this is used to store the I2C address of each child on the bus.
+
+This is all handled automatically by dtoc::
+
+   #include <asm/i2c.h>
+   u8 _sandbox_i2c_priv_i2c_at_0[sizeof(struct sandbox_i2c_priv)]
+      __attribute__ ((section (".priv_data")));
+   #include <i2c.h>
+   u8 _sandbox_i2c_uc_priv_i2c_at_0[sizeof(struct dm_i2c_bus)]
+      __attribute__ ((section (".priv_data")));
+
+   DM_DEVICE_INST(i2c_at_0) = {
+      .driver      = DM_DRIVER_REF(sandbox_i2c),
+      .name      = "sandbox_i2c",
+      .plat_   = &dtv_i2c_at_0,
+      .priv_      = _sandbox_i2c_priv_i2c_at_0,
+      .uclass   = DM_UCLASS_REF(i2c),
+      .uclass_priv_ = _sandbox_i2c_uc_priv_i2c_at_0,
+     ...
+
+Part of driver, for reference::
+
+   static const struct udevice_id sandbox_i2c_ids[] = {
+      { .compatible = "sandbox,i2c" },
+      { }
+   };
+
+   U_BOOT_DRIVER(sandbox_i2c) = {
+      .name   = "sandbox_i2c",
+      .id   = UCLASS_I2C,
+      .of_match = sandbox_i2c_ids,
+      .ops   = &sandbox_i2c_ops,
+      .priv_auto   = sizeof(struct sandbox_i2c_priv),
+   };
+
+Part of I2C uclass, for reference::
+
+   UCLASS_DRIVER(i2c) = {
+      .id         = UCLASS_I2C,
+      .name       = "i2c",
+      .flags      = DM_UC_FLAG_SEQ_ALIAS,
+      .post_bind  = i2c_post_bind,
+      .pre_probe  = i2c_pre_probe,
+      .post_probe = i2c_post_probe,
+      .per_device_auto   = sizeof(struct dm_i2c_bus),
+      .per_child_plat_auto   = sizeof(struct dm_i2c_chip),
+      .child_post_bind = i2c_child_post_bind,
+   };
+
+Here, `_sandbox_i2c_uc_priv_i2c_at_0` is required by the uclass but is declared
+in the device, as required by driver model. The required header file is included
+so that the code will compile without errors. A similar mechanism is used for
+child devices, but is not shown by this example.
+
+It would not be that useful to avoid binding devices but still need to allocate
+uclasses at runtime. So dtoc generates uclass instances as well::
+
+   struct list_head uclass_head = {
+      .prev = &DM_UCLASS_REF(serial)->sibling_node,
+      .next = &DM_UCLASS_REF(clk)->sibling_node,
+   };
+
+   DM_UCLASS_INST(clk) = {
+      .uc_drv      = DM_UCLASS_DRIVER_REF(clk),
+      .sibling_node   = {
+         .prev = &uclass_head,
+         .next = &DM_UCLASS_REF(i2c)->sibling_node,
+      },
+      .dev_head   = {
+         .prev = &DM_DEVICE_REF(clk_sbox)->uclass_node,
+         .next = &DM_DEVICE_REF(clk_fixed)->uclass_node,
+      },
+   };
+
+At the top is the list head. Driver model uses this on start-up, instead of
+creating its own.
+
+Below that are a set of `DM_UCLASS_INST()` macros, each declaring a
+`struct uclass`. The doubly linked lists work as for devices.
+
+All private data is placed into a `.priv_data` section so that it is contiguous
+in the resulting output binary.
+
+
+Indexes
+-------
+
+U-Boot stores drivers, devices and many other things in linker_list structures.
+These are sorted by name, so dtoc knows the order that they will appear when
+the linker runs. Each driver_info / udevice is referenced by its index in the
+linker_list array, called 'idx' in the code.
+
+When CONFIG_OF_PLATDATA_INST is enabled, idx is the udevice index, otherwise it
+is the driver_info index. In either case, indexes are used to reference devices
+using device_get_by_ofplat_idx(). This allows phandles to work as expected.
+
+
+Phases
+------
+
+U-Boot operates in several phases, typically TPL, SPL and U-Boot proper.
+The latter does not use dtoc.
+
+In some rare cases different drivers are used for two phases. For example,
+in TPL it may not be necessary to use the full PCI subsystem, so a simple
+driver can be used instead.
+
+This works in the build system simply by compiling in one driver or the
+other (e.g. PCI driver + uclass for SPL; simple_bus for TPL). But dtoc has
+no way of knowing which code is compiled in for which phase, since it does
+not inspect Makefiles or dependency graphs.
+
+So to make this work for dtoc, we need to be able to explicitly mark
+drivers with their phase. This is done by adding a macro to the driver::
+
+   /* code in tpl.c only compiled into TPL */
+   U_BOOT_DRIVER(pci_x86) = {
+      .name   = "pci_x86",
+      .id   = UCLASS_SIMPLE_BUS,
+      .of_match = of_match_ptr(tpl_fake_pci_ids),
+      DM_PHASE(tpl)
+   };
+
+
+   /* code in pci_x86.c compiled into SPL and U-Boot proper */
+   U_BOOT_DRIVER(pci_x86) = {
+      .name   = "pci_x86",
+      .id   = UCLASS_PCI,
+      .of_match = pci_x86_ids,
+      .ops   = &pci_x86_ops,
+   };
+
+
+Notice that the second driver has the same name but no DM_PHASE(), so it will be
+used for SPL and U-Boot.
+
+Note also that this only affects the code generated by dtoc. You still need to
+make sure that only the required driver is build into each phase.
+
+
+Header files
+------------
+
+With OF_PLATDATA_INST, dtoc must include the correct header file in the
+generated code for any structs that are used, so that the code will compile.
+For example, if `struct ns16550_plat` is used, the code must include the
+`ns16550.h` header file.
+
+Typically dtoc can detect the header file needed for a driver by looking
+for the structs that it uses. For example, if a driver as a `.priv_auto`
+that uses `struct ns16550_plat`, then dtoc can search header files for the
+definition of that struct and use the file.
+
+In some cases, enums are used in drivers, typically with the `.data` field
+of `struct udevice_id`. Since dtoc does not support searching for these,
+you must use the `DM_HDR()` macro to tell dtoc which header to use. This works
+as a macro included in the driver definition::
+
+   static const struct udevice_id apl_syscon_ids[] = {
+      { .compatible = "intel,apl-punit", .data = X86_SYSCON_PUNIT },
+      { }
+   };
+
+   U_BOOT_DRIVER(intel_apl_punit) = {
+      .name       = "intel_apl_punit",
+      .id         = UCLASS_SYSCON,
+      .of_match   = apl_syscon_ids,
+      .probe      = apl_punit_probe,
+      DM_HEADER(<asm/cpu.h>)    /* for X86_SYSCON_PUNIT */
+   };
+
+
+
+Caveats
+-------
+
+There are various complications with this feature which mean it should only
+be used when strictly necessary, i.e. in SPL with limited memory. Notable
+caveats include:
+
+   - Device tree does not describe data types. But the C code must define a
+     type for each property. These are guessed using heuristics which
+     are wrong in several fairly common cases. For example an 8-byte value
+     is considered to be a 2-item integer array, and is byte-swapped. A
+     boolean value that is not present means 'false', but cannot be
+     included in the structures since there is generally no mention of it
+     in the devicetree file.
+
+   - Naming of nodes and properties is automatic. This means that they follow
+     the naming in the devicetree, which may result in C identifiers that
+     look a bit strange.
+
+   - It is not possible to find a value given a property name. Code must use
+     the associated C member variable directly in the code. This makes
+     the code less robust in the face of devicetree changes. To avoid having
+     a second struct with similar members and names you need to explicitly
+     declare it as an alias with `DM_DRIVER_ALIAS()`.
+
+   - The platform data is provided to drivers as a C structure. The driver
+     must use the same structure to access the data. Since a driver
+     normally also supports devicetree it must use `#ifdef` to separate
+     out this code, since the structures are only available in SPL. This could
+     be fixed fairly easily by making the structs available outside SPL, so
+     that `IS_ENABLED()` could be used.
+
+   - With CONFIG_OF_PLATDATA_INST all binding happens at build-time, meaning
+     that (by default) it is not possible to call `device_bind()` from C code.
+     This means that all devices must have an associated devicetree node and
+     compatible string. For example if a GPIO device currently creates child
+     devices in its `bind()` method, it will not work with
+     CONFIG_OF_PLATDATA_INST. Arguably this is bad practice anyway and the
+     devicetree binding should be updated to declare compatible strings for
+     the child devices. It is possible to disable OF_PLATDATA_NO_BIND but this
+     is not recommended since it increases code size.
+
+
+Internals
+---------
+
+Generated files
+```````````````
+
+When enabled, dtoc generates the following five files:
+
+include/generated/dt-decl.h (OF_PLATDATA_INST only)
+   Contains declarations for all drivers, devices and uclasses. This allows
+   any `struct udevice`, `struct driver` or `struct uclass` to be located by its
+   name
+
+include/generated/dt-structs-gen.h
+   Contains the struct definitions for the devicetree nodes that are used. This
+   is the same as without OF_PLATDATA_INST
+
+spl/dts/dt-plat.c (only with !OF_PLATDATA_INST)
+   Contains the `U_BOOT_DRVINFO()` declarations that U-Boot uses to bind devices
+   at start-up. See above for an example
+
+spl/dts/dt-device.c (only with OF_PLATDATA_INST)
+   Contains `DM_DEVICE_INST()` declarations for each device that can be used at
+   run-time. These are declared in the file along with any private/platform data
+   that they use. Every device has an idx, as above. Since each device must be
+   part of a double-linked list, the nodes are declared in the code as well.
+
+spl/dts/dt-uclass.c (only with OF_PLATDATA_INST)
+   Contains `DM_UCLASS_INST()` declarations for each uclass that can be used at
+   run-time. These are declared in the file along with any private data
+   associated with the uclass itself (the `.priv_auto` member). Since each
+   uclass must be part of a double-linked list, the nodes are declared in the
+   code as well.
+
+The dt-structs.h file includes the generated file
+`(include/generated/dt-structs.h`) if CONFIG_SPL_OF_PLATDATA is enabled.
+Otherwise (such as in U-Boot proper) these structs are not available. This
+prevents them being used inadvertently. All usage must be bracketed with
+`#if CONFIG_IS_ENABLED(OF_PLATDATA)`.
+
+The dt-plat.c file contains the device declarations and is is built in
+spl/dt-plat.c.
+
+
+CONFIG options
+``````````````
+
+Several CONFIG options are used to control the behaviour of of-platdata, all
+available for both SPL and TPL:
+
+OF_PLATDATA
+   This is the main option which enables the of-platdata feature
+
+OF_PLATDATA_PARENT
+   This allows `device_get_parent()` to work. Without this, all devices exist as
+   direct children of the root node. This option is highly desirable (if not
+   always absolutely essential) for buses such as I2C.
+
+OF_PLATDATA_INST
+   This controls the instantiation of devices at build time. With it disabled,
+   only `U_BOOT_DRVINFO()` records are created, with U-Boot handling the binding
+   in `device_bind()` on start-up. With it enabled, only `DM_DEVICE_INST()` and
+   `DM_UCLASS_INST()` records are created, and `device_bind()` is not needed at
+   runtime.
+
+OF_PLATDATA_NO_BIND
+   This controls whether `device_bind()` is supported. It is enabled by default
+   with OF_PLATDATA_INST since code-size reduction is really the main point of
+   the feature. It can be disabled if needed but is not likely to be supported
+   in the long term.
+
+OF_PLATDATA_DRIVER_RT
+   This controls whether the `struct driver_rt` records are used by U-Boot.
+   Normally when a device is bound, U-Boot stores the device pointer in one of
+   these records. There is one for every `struct driver_info` in the system,
+   i.e. one for every device that is bound from those records. It provides a
+   way to locate a device in the code and is used by
+   `device_get_by_ofplat_idx()`. This option is always enabled with of-platdata,
+   provided OF_PLATDATA_INST is not. In that case the records are useless since
+   we don't have any `struct driver_info` records.
+
+OF_PLATDATA_RT
+   This controls whether the `struct udevice_rt` records are used by U-Boot.
+   It moves the updatable fields from `struct udevice` (currently only `flags`)
+   into a separate structure, allowing the records to be kept in read-only
+   memory. It is generally enabled if OF_PLATDATA_INST is enabled. This option
+   also controls whether the private data is used in situ, or first copied into
+   an allocated region. Again this is to allow the private data declared by
+   dtoc-generated code to be in read-only memory. Note that access to private
+   data must be done via accessor functions, such as `dev_get_priv()`, so that
+   the relocation is handled.
+
+READ_ONLY
+   This indicates that the data generated by dtoc should not be modified. Only
+   a few fields actually do get changed in U-Boot, such as device flags. This
+   option causes those to move into an allocated space (see OF_PLATDATA_RT).
+   Also, since updating doubly linked lists is generally impossible when some of
+   the nodes cannot be updated, OF_PLATDATA_NO_BIND is enabled.
+
+Data structures
+```````````````
+
+A few extra data structures are used with of-platdata:
+
+`struct udevice_rt`
+   Run-time information for devices. When OF_PLATDATA_RT is enabled, this holds
+   the flags for each device, so that `struct udevice` can remain unchanged by
+   U-Boot, and potentially reside in read-only memory. Access to flags is then
+   via functions like `dev_get_flags()` and `dev_or_flags()`. This data
+   structure is allocated on start-up, where the private data is also copied.
+   All flags values start at 0 and any changes are handled by `dev_or_flags()`
+   and `dev_bic_flags()`. It would be more correct for the flags to be set to
+   `DM_FLAG_BOUND`, or perhaps `DM_FLAG_BOUND | DM_FLAG_ALLOC_PDATA`, but since
+   there is no code to bind/unbind devices and no code to allocate/free
+   private data / platform data, it doesn't matter.
+
+`struct driver_rt`
+   Run-time information for `struct driver_info` records. When
+   OF_PLATDATA_DRIVER_RT is enabled, this holds a pointer to the device
+   created by each record. This is needed so that is it possible to locate a
+   device from C code. Specifically, the code can use `DM_DRVINFO_GET(name)` to
+   get a reference to a particular `struct driver_info`, with `name` being the
+   name of the devicetree node. This is very convenient. It is also fast, since
+   no    searching or string comparison is needed. This data structure is
+   allocated    on start-up, filled out by `device_bind()` and used by
+   `device_get_by_ofplat_idx()`.
+
+Other changes
+`````````````
+
+Some other changes are made with of-platdata:
+
+Accessor functions
+   Accessing private / platform data via functions such as `dev_get_priv()` has
+   always been encouraged. With OF_PLATDATA_RT this is essential, since the
+   `priv_` and `plat_`  (etc.) values point to the data generated by dtoc, not
+   the read-write copy that is sometimes made on start-up. Changing the
+   private / platform data  pointers has always been discouraged (the API is
+   marked internal) but with OF_PLATDATA_RT this is not currently supported in
+   general, since it assumes that all such pointers point to the relocated data.
+   Note also that the renaming of struct members to have a trailing underscore
+   was partly done to make people aware that they should not be accessed
+   directly.
+
+`gd->uclass_root_s`
+   Normally U-Boot sets up the head of the uclass list here and makes
+   `gd->uclass_root` point to it. With OF_PLATDATA_INST, dtoc generates a
+   declaration of `uclass_head` in `dt-uclass.c` since it needs to link the
+   head node into the list. In that case, `gd->uclass_root_s` is not used and
+   U-Boot just makes `gd->uclass_root` point to `uclass_head`.
+
+`gd->dm_driver_rt`
+   This holds a pointer to a list of `struct driver_rt` records, one for each
+   `struct driver_info`. The list is in alphabetical order by the name used
+   in `U_BOOT_DRVINFO(name)` and indexed by idx, with the first record having
+   an index of 0. It is only used if OF_PLATDATA_INST is not enabled. This is
+   accessed via macros so that it can be used inside IS_ENABLED(), rather than
+   requiring #ifdefs in the C code when it is not present.
+
+`gd->dm_udevice_rt`
+   This holds a pointer to a list of `struct udevice_rt` records, one for each
+   `struct udevice`. The list is in alphabetical order by the name used
+   in `DM_DEVICE_INST(name)` (a C version of the devicetree node) and indexed by
+   idx, with the first record having an index of 0. It is only used if
+   OF_PLATDATA_INST is enabled. This is accessed via macros so that it can be
+   used inside `IS_ENABLED()`, rather than requiring #ifdefs in the C code when
+   it is not present.
+
+`gd->dm_priv_base`
+   When OF_PLATDATA_RT is enabled, the private/platform data for each device is
+   copied into an allocated region by U-Boot on start-up. This points to that
+   region. All calls to accessor functions (e.g. `dev_get_priv()`) then
+   translate from the pointer provided by the caller (assumed to lie between
+   `__priv_data_start` and `__priv_data_end`) to the new allocated region. This
+   member is accessed via macros so that it can be used inside IS_ENABLED(),
+   rather than required #ifdefs in the C code when it is not present.
+
+`struct udevice->flags_`
+   When OF_PLATDATA_RT is enabled, device flags are no-longer part of
+   `struct udevice`, but are instead kept in `struct udevice_rt`, as described
+   above. Flags are accessed via functions, such as `dev_get_flags()` and
+   `dev_or_flags()`.
+
+`struct udevice->node_`
+   When OF_PLATDATA is enabled, there is no devicetree at runtime, so no need
+   for this field. It is removed, just to save space.
+
+`DM_PHASE`
+   This macro is used to indicate which phase of U-Boot a driver is intended
+   for. See above for details.
+
+`DM_HDR`
+   This macro is used to indicate which header file dtoc should use to allow
+   a driver declaration to compile correctly. See above for details.
+
+`device_get_by_ofplat_idx()`
+   There used to be a function called `device_get_by_driver_info()` which
+   looked up a `struct driver_info` pointer and returned the `struct udevice`
+   that was created from it. It was only available for use with of-platdata.
+   This has been removed in favour of `device_get_by_ofplat_idx()` which uses
+   `idx`, the index of the `struct driver_info` or `struct udevice` in the
+   linker_list. Similarly, the `struct phandle_0_arg` (etc.) structs have been
+   updated to use this index instead of a pointer to `struct driver_info`.
+
+`DM_DRVINFO_GET`
+   This has been removed since we now use indexes to obtain a driver from
+   `struct phandle_0_arg` and the like.
+
+Two-pass binding
+   The original of-platdata tried to order `U_BOOT_DRVINFO()` in the generated
+   files so as to have parents declared ahead of children. This was convenient
+   as it avoided any special code in U-Boot. With OF_PLATDATA_INST this does
+   not work as the idx value relies on using alphabetical order for everything,
+   so that dtoc and U-Boot's linker_lists agree on the idx value. Devices are
+   then bound in order of idx, having no regard to parent/child relationships.
+   For this reason, device binding now hapens in multiple passes, with parents
+   being bound before their children. This is important so that children can
+   find their parents in the bind() method if needed.
+
+Root device
+   The root device is generally bound by U-Boot but with OF_PLATDATA_INST it
+   cannot be, since binding needs to be done at build time. So in this case
+   dtoc sets up a root device using `DM_DEVICE_INST()` in `dt-device.c` and
+   U-Boot makes use of that. When OF_PLATDATA_INST is not enabled, U-Boot
+   generally ignores the root node and does not create a `U_BOOT_DRVINFO()`
+   record for it. This means that the idx numbers used by `struct driver_info`
+   (when OF_PLATDATA_INST is disabled) and the idx numbers used by
+   `struct udevice` (when OF_PLATDATA_INST is enabled) differ, since one has a
+   root node and the other does not. This does not actually matter, since only
+   one of them is actually used for any particular build, but it is worth
+   keeping in mind if comparing index values and switching OF_PLATDATA_INST on
+   and off.
+
+`__priv_data_start` and `__priv_data_end`
+   The private/platform data declared by dtoc is all collected together in
+   a linker section and these symbols mark the start and end of it. This allows
+   U-Boot to relocate the area to a new location if needed (with
+   OF_PLATDATA_RT)
+
+`dm_priv_to_rw()`
+   This function converts a private- or platform-data pointer value generated by
+   dtoc into one that can be used by U-Boot. It is a NOP unless OF_PLATDATA_RT
+   is enabled, in which case it translates the address to the relocated
+   region. See above for more information.
+
+The dm_populate_phandle_data() function that was previous needed has now been
+removed, since dtoc can address the drivers directly from dt-plat.c and does
+not need to fix up things at runtime.
+
+The pylibfdt Python module is used to access the devicetree.

-Compiled-in Device Tree / Platform Data
-=======================================
-
-
-Introduction
-------------
-
-Device tree is the standard configuration method in U-Boot. It is used to
-define what devices are in the system and provide configuration information
-to these devices.
-
-The overhead of adding device tree access to U-Boot is fairly modest,
-approximately 3KB on Thumb 2 (plus the size of the DT itself). This means
-that in most cases it is best to use device tree for configuration.
-
-However there are some very constrained environments where U-Boot needs to
-work. These include SPL with severe memory limitations. For example, some
-SoCs require a 16KB SPL image which must include a full MMC stack. In this
-case the overhead of device tree access may be too great.
-
-It is possible to create platform data manually by defining C structures
-for it, and reference that data in a U_BOOT_DRVINFO() declaration. This
-bypasses the use of device tree completely, effectively creating a parallel
-configuration mechanism. But it is an available option for SPL.
-
-As an alternative, a new 'of-platdata' feature is provided. This converts the
-device tree contents into C code which can be compiled into the SPL binary.
-This saves the 3KB of code overhead and perhaps a few hundred more bytes due
-to more efficient storage of the data.
-
-Note: Quite a bit of thought has gone into the design of this feature.
-However it still has many rough edges and comments and suggestions are
-strongly encouraged! Quite possibly there is a much better approach.
-
-
-Caveats
--------
-
-There are many problems with this features. It should only be used when
-strictly necessary. Notable problems include:
-
-   - Device tree does not describe data types. But the C code must define a
-     type for each property. These are guessed using heuristics which
-     are wrong in several fairly common cases. For example an 8-byte value
-     is considered to be a 2-item integer array, and is byte-swapped. A
-     boolean value that is not present means 'false', but cannot be
-     included in the structures since there is generally no mention of it
-     in the device tree file.
-
-   - Naming of nodes and properties is automatic. This means that they follow
-     the naming in the device tree, which may result in C identifiers that
-     look a bit strange.
-
-   - It is not possible to find a value given a property name. Code must use
-     the associated C member variable directly in the code. This makes
-     the code less robust in the face of device-tree changes. It also
-     makes it very unlikely that your driver code will be useful for more
-     than one SoC. Even if the code is common, each SoC will end up with
-     a different C struct name, and a likely a different format for the
-     platform data.
-
-   - The platform data is provided to drivers as a C structure. The driver
-     must use the same structure to access the data. Since a driver
-     normally also supports device tree it must use #ifdef to separate
-     out this code, since the structures are only available in SPL.
-
-
-How it works
-------------
-
-The feature is enabled by CONFIG OF_PLATDATA. This is only available in
-SPL/TPL and should be tested with:
-
-.. code-block:: c
-
-    #if CONFIG_IS_ENABLED(OF_PLATDATA)
-
-A new tool called 'dtoc' converts a device tree file either into a set of
-struct declarations, one for each compatible node, and a set of
-U_BOOT_DRVINFO() declarations along with the actual platform data for each
-device. As an example, consider this MMC node:
-
-.. code-block:: none
-
-    sdmmc: dwmmc@ff0c0000 {
-            compatible = "rockchip,rk3288-dw-mshc";
-            clock-freq-min-max = <400000 150000000>;
-            clocks = <&cru HCLK_SDMMC>, <&cru SCLK_SDMMC>,
-                     <&cru SCLK_SDMMC_DRV>, <&cru SCLK_SDMMC_SAMPLE>;
-            clock-names = "biu", "ciu", "ciu_drv", "ciu_sample";
-            fifo-depth = <0x100>;
-            interrupts = <GIC_SPI 32 IRQ_TYPE_LEVEL_HIGH>;
-            reg = <0xff0c0000 0x4000>;
-            bus-width = <4>;
-            cap-mmc-highspeed;
-            cap-sd-highspeed;
-            card-detect-delay = <200>;
-            disable-wp;
-            num-slots = <1>;
-            pinctrl-names = "default";
-            pinctrl-0 = <&sdmmc_clk>, <&sdmmc_cmd>, <&sdmmc_cd>, <&sdmmc_bus4>;
-                vmmc-supply = <&vcc_sd>;
-                status = "okay";
-                u-boot,dm-pre-reloc;
-        };
-
-
-Some of these properties are dropped by U-Boot under control of the
-CONFIG_OF_SPL_REMOVE_PROPS option. The rest are processed. This will produce
-the following C struct declaration:
-
-.. code-block:: c
-
-    struct dtd_rockchip_rk3288_dw_mshc {
-            fdt32_t         bus_width;
-            bool            cap_mmc_highspeed;
-            bool            cap_sd_highspeed;
-            fdt32_t         card_detect_delay;
-            fdt32_t         clock_freq_min_max[2];
-            struct phandle_1_arg clocks[4];
-            bool            disable_wp;
-            fdt32_t         fifo_depth;
-            fdt32_t         interrupts[3];
-            fdt32_t         num_slots;
-            fdt32_t         reg[2];
-            fdt32_t         vmmc_supply;
-    };
-
-and the following device declarations:
-
-.. code-block:: c
-
-    /* Node /clock-controller@ff760000 index 0 */
-    ...
-
-    /* Node /dwmmc@ff0c0000 index 2 */
-    static struct dtd_rockchip_rk3288_dw_mshc dtv_dwmmc_at_ff0c0000 = {
-            .fifo_depth             = 0x100,
-            .cap_sd_highspeed       = true,
-            .interrupts             = {0x0, 0x20, 0x4},

-
-The device is then instantiated at run-time and the platform data can be
-accessed using:
-
-.. code-block:: c
-
-    struct udevice *dev;
-    struct dtd_rockchip_rk3288_dw_mshc *plat = dev_get_plat(dev);
-
-This avoids the code overhead of converting the device tree data to
-platform data in the driver. The of_to_plat() method should
-therefore do nothing in such a driver.
-
-Note that for the platform data to be matched with a driver, the 'name'
-property of the U_BOOT_DRVINFO() declaration has to match a driver declared
-via U_BOOT_DRIVER(). This effectively means that a U_BOOT_DRIVER() with a
-'name' corresponding to the devicetree 'compatible' string (after converting
-it to a valid name for C) is needed, so a dedicated driver is required for
-each 'compatible' string.
-
-In order to make this a bit more flexible DM_DRIVER_ALIAS macro can be
-used to declare an alias for a driver name, typically a 'compatible' string.
-This macro produces no code, but it is by dtoc tool.
-
-The parent_idx is the index of the parent driver_info structure within its
-linker list (instantiated by the U_BOOT_DRVINFO() macro). This is used to support
-dev_get_parent().
-
-During the build process dtoc parses both U_BOOT_DRIVER and DM_DRIVER_ALIAS
-to build a list of valid driver names and driver aliases. If the 'compatible'
-string used for a device does not not match a valid driver name, it will be
-checked against the list of driver aliases in order to get the right driver
-name to use. If in this step there is no match found a warning is issued to
-avoid run-time failures.
-
-Where a node has multiple compatible strings, a #define is used to make them
-equivalent, e.g.:
-
-.. code-block:: c
-
-    #define dtd_rockchip_rk3299_dw_mshc dtd_rockchip_rk3288_dw_mshc
-
-
-Converting of-platdata to a useful form
----------------------------------------
-
-Of course it would be possible to use the of-platdata directly in your driver
-whenever configuration information is required. However this means that the
-driver will not be able to support device tree, since the of-platdata
-structure is not available when device tree is used. It would make no sense
-to use this structure if device tree were available, since the structure has
-all the limitations metioned in caveats above.
-
-Therefore it is recommended that the of-platdata structure should be used
-only in the probe() method of your driver. It cannot be used in the
-of_to_plat() method since this is not called when platform data is
-already present.
-
-
-How to structure your driver
-----------------------------
-
-Drivers should always support device tree as an option. The of-platdata
-feature is intended as a add-on to existing drivers.
-
-Your driver should convert the plat struct in its probe() method. The
-existing device tree decoding logic should be kept in the
-of_to_plat() method and wrapped with #if.
-
-For example:
-
-.. code-block:: c
-
-    #include <dt-structs.h>
-
-    struct mmc_plat {
-    #if CONFIG_IS_ENABLED(OF_PLATDATA)
-            /* Put this first since driver model will copy the data here */
-            struct dtd_mmc dtplat;
-    #endif
-            /*
-             * Other fields can go here, to be filled in by decoding from
-             * the device tree (or the C structures when of-platdata is used).
-             */
-            int fifo_depth;
-    };
-
-    static int mmc_of_to_plat(struct udevice *dev)
-    {
-    #if !CONFIG_IS_ENABLED(OF_PLATDATA)
-            /* Decode the device tree data */
-            struct mmc_plat *plat = dev_get_plat(dev);
-            const void *blob = gd->fdt_blob;
-            int node = dev_of_offset(dev);
-
-            plat->fifo_depth = fdtdec_get_int(blob, node, "fifo-depth", 0);
-    #endif
-
-            return 0;
-    }
-
-    static int mmc_probe(struct udevice *dev)
-    {
-            struct mmc_plat *plat = dev_get_plat(dev);
-
-    #if CONFIG_IS_ENABLED(OF_PLATDATA)
-            /* Decode the of-platdata from the C structures */
-            struct dtd_mmc *dtplat = &plat->dtplat;
-
-            plat->fifo_depth = dtplat->fifo_depth;
-    #endif
-            /* Set up the device from the plat data */
-            writel(plat->fifo_depth, ...)
-    }
-
-    static const struct udevice_id mmc_ids[] = {
-            { .compatible = "vendor,mmc" },
-            { }
-    };
-
-    U_BOOT_DRIVER(mmc_drv) = {
-            .name           = "mmc_drv",
-            .id             = UCLASS_MMC,
-            .of_match       = mmc_ids,
-            .of_to_plat = mmc_of_to_plat,
-            .probe          = mmc_probe,
-            .priv_auto = sizeof(struct mmc_priv),
-            .plat_auto = sizeof(struct mmc_plat),
-    };
-
-    DM_DRIVER_ALIAS(mmc_drv, vendor_mmc) /* matches compatible string */
-
-Note that struct mmc_plat is defined in the C file, not in a header. This
-is to avoid needing to include dt-structs.h in a header file. The idea is to
-keep the use of each of-platdata struct to the smallest possible code area.
-There is just one driver C file for each struct, that can convert from the
-of-platdata struct to the standard one used by the driver.
-
-In the case where SPL_OF_PLATDATA is enabled, plat_auto is
-still used to allocate space for the platform data. This is different from
-the normal behaviour and is triggered by the use of of-platdata (strictly
-speaking it is a non-zero plat_size which triggers this).
-
-The of-platdata struct contents is copied from the C structure data to the
-start of the newly allocated area. In the case where device tree is used,
-the platform data is allocated, and starts zeroed. In this case the
-of_to_plat() method should still set up the platform data (and the
-of-platdata struct will not be present).
-
-SPL must use either of-platdata or device tree. Drivers cannot use both at
-the same time, but they must support device tree. Supporting of-platdata is
-optional.
-
-The device tree becomes in accessible when CONFIG_SPL_OF_PLATDATA is enabled,
-since the device-tree access code is not compiled in. A corollary is that
-a board can only move to using of-platdata if all the drivers it uses support
-it. There would be little point in having some drivers require the device
-tree data, since then libfdt would still be needed for those drivers and
-there would be no code-size benefit.
-
-Internals
----------
-
-The dt-structs.h file includes the generated file
-(include/generated//dt-structs.h) if CONFIG_SPL_OF_PLATDATA is enabled.
-Otherwise (such as in U-Boot proper) these structs are not available. This
-prevents them being used inadvertently. All usage must be bracketed with
-#if CONFIG_IS_ENABLED(OF_PLATDATA).
-
-The dt-plat.c file contains the device declarations and is is built in
-spl/dt-plat.c.
-
-The dm_populate_phandle_data() function that was previous needed has now been
-removed, since dtoc can address the drivers directly from dt-plat.c and does
-not need to fix up things at runtime.
-
-The pylibfdt Python module is used to access the devicetree.

 Introduction
-------------
+============
 
 Firmware often consists of several components which must be packaged together.
 For example, we may have SPL, U-Boot, a device tree and an environment area
 grouped together and placed in MMC flash. When the system starts, it must be
 able to find these pieces.
 
-So far U-Boot has not provided a way to handle creating such images in a
-general way. Each SoC does what it needs to build an image, often packing or
-concatenating images in the U-Boot build system.
-
-Binman aims to provide a mechanism for building images, from simple
-SPL + U-Boot combinations, to more complex arrangements with many parts.
+Building firmware should be separate from packaging it. Many of the complexities
+of modern firmware build systems come from trying to do both at once. With
+binman, you build all the pieces that are needed, using whatever assortment of
+projects and build systems are needed, then use binman to stitch everything
+together.
 
 
 What it does
 ------------
 
 Binman reads your board's device tree and finds a node which describes the
-required image layout. It uses this to work out what to place where. The
-output file normally contains the device tree, so it is in principle possible
-to read an image and extract its constituent parts.

+
+Binman provides a mechanism for building images, from simple SPL + U-Boot
+combinations, to more complex arrangements with many parts. It also allows
+users to inspect images, extract and replace binaries within them, repacking if
+needed.
 
 
 Features
 --------
 
-So far binman is pretty simple. It supports binary blobs, such as 'u-boot',
-'spl' and 'fdt'. It supports empty entries (such as setting to 0xff). It can
-place entries at a fixed location in the image, or fit them together with
-suitable padding and alignment. It provides a way to process binaries before
-they are included, by adding a Python plug-in. The device tree is available
-to U-Boot at run-time so that the images can be interpreted.
+Apart from basic padding, alignment and positioning features, Binman supports
+hierarchical images, compression, hashing and dealing with the binary blobs
+which are a sad trend in open-source firmware at present.
 
-Binman can update the device tree with the final location of everything when it
-is done. Entry positions can be provided to U-Boot SPL as run-time symbols,
-avoiding device-tree code overhead.
+Executable binaries can access the location of other binaries in an image by
+using special linker symbols (zero-overhead but somewhat limited) or by reading
+the devicetree description of the image.
 
-Binman can also support incorporating filesystems in the image if required.
-For example x86 platforms may use CBFS in some cases.
+Binman is designed primarily for use with U-Boot and associated binaries such
+as ARM Trusted Firmware, but it is suitable for use with other projects, such
+as Zephyr. Binman also provides facilities useful in Chromium OS, such as CBFS,
+vblocks and and the like.

+Access to binman entry offsets at run time (symbols)
+----------------------------------------------------
+
+Binman assembles images and determines where each entry is placed in the image.
+This information may be useful to U-Boot at run time. For example, in SPL it
+is useful to be able to find the location of U-Boot so that it can be executed
+when SPL is finished.
+
+Binman allows you to declare symbols in the SPL image which are filled in
+with their correct values during the build. For example::
+
+    binman_sym_declare(ulong, u_boot_any, image_pos);
+
+declares a ulong value which will be assigned to the image-pos of any U-Boot
+image (u-boot.bin, u-boot.img, u-boot-nodtb.bin) that is present in the image.
+You can access this value with something like::
+
+    ulong u_boot_offset = binman_sym(ulong, u_boot_any, image_pos);
+
+Thus u_boot_offset will be set to the image-pos of U-Boot in memory, assuming
+that the whole image has been loaded, or is available in flash. You can then
+jump to that address to start U-Boot.
+
+At present this feature is only supported in SPL and TPL. In principle it is
+possible to fill in such symbols in U-Boot proper, as well, but a future C
+library is planned for this instead, to read from the device tree.
+
+As well as image-pos, it is possible to read the size of an entry and its
+offset (which is the start position of the entry within its parent).
+
+A small technical note: Binman automatically adds the base address of the image
+(i.e. __image_copy_start) to the value of the image-pos symbol, so that when the
+image is loaded to its linked address, the value will be correct and actually
+point into the image.
+
+For example, say SPL is at the start of the image and linked to start at address
+80108000. If U-Boot's image-pos is 0x8000 then binman will write an image-pos
+for U-Boot of 80110000 into the SPL binary, since it assumes the image is loaded
+to 80108000, with SPL at 80108000 and U-Boot at 80110000.
+
+For x86 devices (with the end-at-4gb property) this base address is not added
+since it is assumed that images are XIP and the offsets already include the
+address.
+
+
+Access to binman entry offsets at run time (fdt)
+------------------------------------------------
+
+Binman can update the U-Boot FDT to include the final position and size of
+each entry in the images it processes. The option to enable this is -u and it
+causes binman to make sure that the 'offset', 'image-pos' and 'size' properties
+are set correctly for every entry. Since it is not necessary to specify these in
+the image definition, binman calculates the final values and writes these to
+the device tree. These can be used by U-Boot at run-time to find the location
+of each entry.
+
+Alternatively, an FDT map entry can be used to add a special FDT containing
+just the information about the image. This is preceded by a magic string so can
+be located anywhere in the image. An image header (typically at the start or end
+of the image) can be used to point to the FDT map. See fdtmap and image-header
+entries for more information.
+
+
+Map files
+---------
+
+The -m option causes binman to output a .map file for each image that it
+generates. This shows the offset and size of each entry. For example::
+
+      Offset      Size  Name
+    00000000  00000028  main-section
+     00000000  00000010  section@0
+      00000000  00000004  u-boot
+     00000010  00000010  section@1
+      00000000  00000004  u-boot
+
+This shows a hierarchical image with two sections, each with a single entry. The
+offsets of the sections are absolute hex byte offsets within the image. The
+offsets of the entries are relative to their respective sections. The size of
+each entry is also shown, in bytes (hex). The indentation shows the entries
+nested inside their sections.
+
+
+Passing command-line arguments to entries
+-----------------------------------------
+
+Sometimes it is useful to pass binman the value of an entry property from the
+command line. For example some entries need access to files and it is not
+always convenient to put these filenames in the image definition (device tree).
+
+The-a option supports this::
+
+    -a<prop>=<value>
+
+where::
+
+    <prop> is the property to set
+    <value> is the value to set it to
+
+Not all properties can be provided this way. Only some entries support it,
+typically for filenames.
+

 Image description format

-below:
-
-	binman {

-		pad-byte = <0xff>;
-		blob {
-			filename = "spl/sunxi-spl.bin";
-		};
-		u-boot {
-			offset = <CONFIG_SPL_PAD_TO>;
-		};
-	};

+        u-boot {
+            offset = <CONFIG_SPL_PAD_TO>;
+        };

+
+    Adding this property causes the original offset and size values in the
+    image description to be stored in the FDT and fdtmap.
+
+
+Hashing Entries
+---------------
+
+It is possible to ask binman to hash the contents of an entry and write that
+value back to the device-tree node. For example::
+
+    binman {
+        u-boot {
+            hash {
+                algo = "sha256";
+            };
+        };
+    };
+
+Here, a new 'value' property will be written to the 'hash' node containing
+the hash of the 'u-boot' entry. Only SHA256 is supported at present. Whole
+sections can be hased if desired, by adding the 'hash' node to the section.
+
+The has value can be chcked at runtime by hashing the data actually read and
+comparing this has to the value in the device tree.
+
+
+Expanded entries
+----------------
+
+Binman automatically replaces 'u-boot' with an expanded version of that, i.e.
+'u-boot-expanded'. This means that when you write::
+
+    u-boot {
+    };
+
+you actually get::
+
+    u-boot {
+        type = "u-boot-expanded';
+    };
+
+which in turn expands to::
+
+    u-boot {
+        type = "section";
+
+        u-boot-nodtb {
+        };
+
+        u-boot-dtb {
+        };
+    };
+
+U-Boot's various phase binaries actually comprise two or three pieces.
+For example, u-boot.bin has the executable followed by a devicetree.
+
+With binman we want to be able to update that devicetree with full image
+information so that it is accessible to the executable. This is tricky
+if it is not clear where the devicetree starts.
+
+The above feature ensures that the devicetree is clearly separated from the
+U-Boot executable and can be updated separately by binman as needed. It can be
+disabled with the --no-expanded flag if required.
+
+The same applies for u-boot-spl and u-boot-spl. In those cases, the expansion
+includes the BSS padding, so for example::
+
+    spl {
+        type = "u-boot-spl"
+    };
+
+you actually get::
+
+    spl {
+        type = "u-boot-expanded';
+    };
+
+which in turn expands to::
+
+    spl {
+        type = "section";
+
+        u-boot-spl-nodtb {
+        };
+
+        u-boot-spl-bss-pad {
+        };
+
+        u-boot-spl-dtb {
+        };
+    };
+
+Of course we should not expand SPL if it has no devicetree. Also if the BSS
+padding is not needed (because BSS is in RAM as with CONFIG_SPL_SEPARATE_BSS),
+the 'u-boot-spl-bss-pad' subnode should not be created. The use of the expaned
+entry type is controlled by the UseExpanded() method. In the SPL case it checks
+the 'spl-dtb' entry arg, which is 'y' or '1' if SPL has a devicetree.
+
+For the BSS case, a 'spl-bss-pad' entry arg controls whether it is present. All
+entry args are provided by the U-Boot Makefile.
+
+
+Compression
+-----------
+
+Binman support compression for 'blob' entries (those of type 'blob' and

+
+    blob {
+        filename = "datafile";
+        compress = "lz4";
+    };
+
+The entry will then contain the compressed data, using the 'lz4' compression
+algorithm. Currently this is the only one that is supported. The uncompressed
+size is written to the node in an 'uncomp-size' property, if -u is used.
+
+Compression is also supported for sections. In that case the entire section is
+compressed in one block, including all its contents. This means that accessing
+an entry from the section required decompressing the entire section. Also, the
+size of a section indicates the space that it consumes in its parent section
+(and typically the image). With compression, the section may contain more data,
+and the uncomp-size property indicates that, as above. The contents of the
+section is compressed first, before any padding is added. This ensures that the
+padding itself is not compressed, which would be a waste of time.

-   # u_boot_dtsi_options_debug = $(u_boot_dtsi_options_raw)
-
-
-Access to binman entry offsets at run time (symbols)
-----------------------------------------------------
-
-Binman assembles images and determines where each entry is placed in the image.
-This information may be useful to U-Boot at run time. For example, in SPL it
-is useful to be able to find the location of U-Boot so that it can be executed
-when SPL is finished.
-
-Binman allows you to declare symbols in the SPL image which are filled in
-with their correct values during the build. For example:
-
-    binman_sym_declare(ulong, u_boot_any, image_pos);
-
-declares a ulong value which will be assigned to the image-pos of any U-Boot
-image (u-boot.bin, u-boot.img, u-boot-nodtb.bin) that is present in the image.
-You can access this value with something like:
-
-    ulong u_boot_offset = binman_sym(ulong, u_boot_any, image_pos);
-
-Thus u_boot_offset will be set to the image-pos of U-Boot in memory, assuming
-that the whole image has been loaded, or is available in flash. You can then
-jump to that address to start U-Boot.
-
-At present this feature is only supported in SPL and TPL. In principle it is
-possible to fill in such symbols in U-Boot proper, as well, but a future C
-library is planned for this instead, to read from the device tree.
-
-As well as image-pos, it is possible to read the size of an entry and its
-offset (which is the start position of the entry within its parent).
-
-A small technical note: Binman automatically adds the base address of the image
-(i.e. __image_copy_start) to the value of the image-pos symbol, so that when the
-image is loaded to its linked address, the value will be correct and actually
-point into the image.
-
-For example, say SPL is at the start of the image and linked to start at address
-80108000. If U-Boot's image-pos is 0x8000 then binman will write an image-pos
-for U-Boot of 80110000 into the SPL binary, since it assumes the image is loaded
-to 80108000, with SPL at 80108000 and U-Boot at 80110000.
-
-For x86 devices (with the end-at-4gb property) this base address is not added
-since it is assumed that images are XIP and the offsets already include the
-address.
-
-
-Access to binman entry offsets at run time (fdt)
-------------------------------------------------
-
-Binman can update the U-Boot FDT to include the final position and size of
-each entry in the images it processes. The option to enable this is -u and it
-causes binman to make sure that the 'offset', 'image-pos' and 'size' properties
-are set correctly for every entry. Since it is not necessary to specify these in
-the image definition, binman calculates the final values and writes these to
-the device tree. These can be used by U-Boot at run-time to find the location
-of each entry.
-
-Alternatively, an FDT map entry can be used to add a special FDT containing
-just the information about the image. This is preceded by a magic string so can
-be located anywhere in the image. An image header (typically at the start or end
-of the image) can be used to point to the FDT map. See fdtmap and image-header
-entries for more information.
-
-
-Compression
------------
-
-Binman support compression for 'blob' entries (those of type 'blob' and
-derivatives). To enable this for an entry, add a 'compress' property:
-
-    blob {
-        filename = "datafile";
-        compress = "lz4";
-    };
-
-The entry will then contain the compressed data, using the 'lz4' compression
-algorithm. Currently this is the only one that is supported. The uncompressed
-size is written to the node in an 'uncomp-size' property, if -u is used.
-
-Compression is also supported for sections. In that case the entire section is
-compressed in one block, including all its contents. This means that accessing
-an entry from the section required decompressing the entire section. Also, the
-size of a section indicates the space that it consumes in its parent section
-(and typically the image). With compression, the section may contain more data,
-and the uncomp-size property indicates that, as above. The contents of the
-section is compressed first, before any padding is added. This ensures that the
-padding itself is not compressed, which would be a waste of time.
-
-
-Map files
----------
-
-The -m option causes binman to output a .map file for each image that it
-generates. This shows the offset and size of each entry. For example:
-
-      Offset      Size  Name
-    00000000  00000028  main-section
-     00000000  00000010  section@0
-      00000000  00000004  u-boot
-     00000010  00000010  section@1
-      00000000  00000004  u-boot
-
-This shows a hierarchical image with two sections, each with a single entry. The
-offsets of the sections are absolute hex byte offsets within the image. The
-offsets of the entries are relative to their respective sections. The size of
-each entry is also shown, in bytes (hex). The indentation shows the entries
-nested inside their sections.
-
-
-Passing command-line arguments to entries
------------------------------------------
-
-Sometimes it is useful to pass binman the value of an entry property from the
-command line. For example some entries need access to files and it is not
-always convenient to put these filenames in the image definition (device tree).
-
-The-a option supports this:
-
-    -a<prop>=<value>
-
-where
-
-    <prop> is the property to set
-    <value> is the value to set it to
-
-Not all properties can be provided this way. Only some entries support it,
-typically for filenames.

+the end of it so may not be able to work without it, assuming TPL needs
+a device tree to operate on your platform. You can add a u-boot-tpl-dtb
+entry after this one, or use a u-boot-tpl entry instead, which normally
+expands to a section containing u-boot-tpl-dtb, u-boot-tpl-bss-pad and
+u-boot-tpl-dtb
+
+TPL can access binman symbols at runtime. See:
+
+    'Access to binman entry offsets at run time (symbols)'
+
+in the binman README for more information.
+
+The ELF file 'tpl/u-boot-tpl' must also be available for this to work, since
+binman uses that to look up symbols to write into the TPL binary.
