2022-08-12dm: core: Introduce support for multiple treesSimon Glass3-2/+49
At present ofnode only works with a single device tree, for the most part. This is the control FDT used by U-Boot. When booting an OS we may obtain a different device tree and want to modify it. Add some initial support for this into the ofnode API. Note that we don't permit aliases in this other device tree, since the of_access implementation maintains a list of aliases collected at start-up. Also, we don't need aliases to do fixups in the other FDT. So make sure that flat tree and live tree processing are consistent in this area. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-08-12dm: core: Add a note about how livetree updates workSimon Glass1-1/+2
The unflattening algorithm results in a single block of memory being allocated for the whole tree. When writing new properties, these are allocated new memory outside that block. When the block is freed, the allocated properties remain. Document how this works and the potential memory leak, as well as mentioning that updating the livetree is actually supported now.

2022-08-12dm: core: Split out the declaration of ofnodeSimon Glass2-60/+73
This is used by a lot of files, but ofnode.h needs to include a lot of header files. This can create dependency cycles, particularly with global_data.h which must include various declarations. Split the core delcarations into a separate file to fix this. Signed-off-by: Simon Glass <sjg@chromium.org>

2022-07-28pinctrl: Add new function pinctrl_generic_set_state_prefix()Pali Rohár1-0/+2
This new function pinctrl_generic_set_state_prefix() behaves like pinctrl_generic_set_state() but it takes third string argument which is used as the prefix for each device tree string property. This is needed for Marvell pinctrl drivers, becase Linux device tree files have pinmux properties prefixed by "marvell," string. This change allows to use generic U-Boot pinctrl functions for Armada 38x pinctrl driver without need to copy+paste of the majority U-Boot pinctrl code.

2022-06-28dm: core: Support accessing core tagsSimon Glass2-1/+37
At present tag numbers are only allocated for non-core data, meaning that the 'core' data, like priv and plat, are accessed through dedicated functions. For debugging and consistency it is convenient to use tags for this 'core' data too. Add support for this, with new tag numbers and functions to access the pointer and size for each. Update one of the test drivers so that the uclass-private data can be tested here. There is some code duplication with functions like device_alloc_priv() but this is not addressed for now. At some point, some rationalisation may help to reduce code size, but more thought it needed on that. Signed-off-by: Simon Glass <sjg@chromium.org>

2022-04-28dm: core: Add DM_FLAG_PROBE_AFTER_BIND flagMarek Vasut1-0/+3
Introduce DM_FLAG_PROBE_AFTER_BIND flag, which can be set by driver or uclass in .bind(), to indicate such driver instance should be probe()d once binding of all devices is complete. This is useful in case the driver determines that hardware initialization is mandatory on boot, and such initialization happens only in probe(). This also solves the inability to call device_probe() from .bind().

2022-04-25Merge branch '2022-04-25-initial-implementation-of-stdboot'Tom Rini4-4/+23
To quote the author: The bootflow feature provide a built-in way for U-Boot to automatically boot an Operating System without custom scripting and other customisation. This is called 'standard boot' since it provides a standard way for U-Boot to boot a distro, without scripting. It introduces the following concepts: - bootdev - a device which can hold a distro - bootmeth - a method to scan a bootdev to find bootflows (owned by U-Boot) - bootflow - a description of how to boot (owned by the distro) This series provides an implementation of these, enabled to scan for bootflows from MMC, USB and Ethernet. It supports the existing distro boot as well as the EFI loader flow (bootefi/bootmgr). It works similiarly to the existing script-based approach, but is native to U-Boot. With this we can boot on a Raspberry Pi 3 with just one command: bootflow scan -lb which means to scan, listing (-l) each bootflow and trying to boot each one (-b). The final patch shows this. With a standard way to identify boot devices, booting become easier. It also should be possible to support U-Boot scripts, for backwards compatibility only. ... The design is described in these two documents: https://drive.google.com/file/d/1ggW0KJpUOR__vBkj3l61L2dav4ZkNC12/view?usp=sharing https://drive.google.com/file/d/1kTrflO9vvGlKp-ZH_jlgb9TY3WYG6FF9/view?usp=sharing
2022-04-25bootstd: Add the bootmeth uclass and helpersSimon Glass1-0/+1
A bootmeth is a method of locating an operating system. For now, just add the uclass itself. Drivers for particular bootmeths are added later. If no bootmeths devices are included in the devicetree, create them automatically. This avoids the need for boilerplate in the devicetree files. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-04-25bootstd: Add the bootdev uclassSimon Glass1-0/+1
A 'bootdev' is a device which can be used to boot an operating system. It is a child of the media device (e.g. MMC) which handles reading files from that device, such as a bootflow file. Add a uclass for bootdev and the various helpers needed to make it work. Also add a binding file, empty for now. Signed-off-by: Simon Glass <sjg@chromium.org>

2022-04-18dm: core: Deal with a wrinkle with linker listsWIP/2022-04-18-dm-reducing-spl-memory-usageSimon Glass1-0/+8
When every member of a linker list is aligned by the compiler, we can no longer rely on the sizeof of the struct to determine the number of entries. For example, if the struct size is 0x90 but every entry is aligned to 0xa0 by the compiler, the linker list entries takes more space in memory and the calculation of the number of entries is incorrect. For example, we may see 0x12 entries when there are only 0x11. This is a real problem. There may be a general solution, although I cannot currently think of one. So far it only bites with OF_PLATDATA_RT which creates a pointer to each entry of the 'struct udevice' linker_list. This does not happen without that option, so it only affects SPL. Work around it by manually calculating the aligned size of struct udevice, then using that for the n_ent calculation.
