 6. CONFIG_ARM64 instead of CONFIG_ARMV8 is used to distinguish aarch64 and
    aarch32 specific codes.
 
+MMU
+---
+
+U-Boot uses a simple page table for MMU setup. It uses the smallest number of bits
+possible for the virtual address based on the maximum memory address (see the logic
+in ``get_tcr()``). If this is less than 39 bits, the MMU will use only 3 levels for
+address translation.
+
+As with all platforms, U-Boot on ARM64 uses a 1:1 mapping of virtual to physical addresses.
+In general, the memory map is expected to remain static once the MMU is enabled.
+
+Software pagetable walker
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+It is possible to debug the pagetable generated by U-Boot with the built in
+``dump_pagetable()`` and ``walk_pagetable()`` functions (the former being a simple
+wrapper for the latter). For example the following can be added to ``setup_all_pgtables()``
+after the first call to ``setup_pgtables()``:
+
+.. code-block:: c
+
+    dump_pagetable(gd->arch.tlb_addr, get_tcr(NULL, NULL));
+
+.. kernel-doc:: arch/arm/cpu/armv8/cache_v8.c
+   :identifiers: __pagetable_walk pagetable_print_entry
+
+The pagetable walker can be used as follows:
+
+.. kernel-doc:: arch/arm/include/asm/armv8/mmu.h
+   :identifiers: pte_walker_cb_t walk_pagetable dump_pagetable
+
+This will result in a print like the following:

+.. code-block:: text

+ * on-module eMMC
+ * SD card (on a baseboard) via edge connector
+ * Gigabit Ethernet with on-module GbE PHY
+ * HDMI/eDP
+ * MIPI-DSI
+ * 4x MIPI-CSI (3x on FPC connectors, 1x over Q7)
+ * HDMI input over FPC connector
+ * CAN
+ * USB
+   - 1x USB 3.0 dual-role (direct connection)
+   - 2x USB 3.0 host + 1x USB 2.0 host
+ * PCIe
+   - 1x PCIe 2.1 Gen3, 4 lanes
+   - 2xSATA / 2x PCIe 2.1 Gen1, 2 lanes
+ * on-module ATtiny816 companion controller, implementing:
+   - low-power RTC functionality (ISL1208 emulation)
+   - fan controller (AMC6821 emulation)
+ * on-module Secure Element with Global Platform 2.2.1 compliant
+   JavaCard environment
+
+Here is the step-by-step to boot to U-Boot on SOM-RK3588-Q7 Tiger from Theobroma
+Systems.

+J722S-EVM Platform
+==================
+
+The J722S is a family of  application processors built for Automotive and
+Linux Application development. J722S family of SoCs is a superset of the
+AM62P SoC family and shares similar memory map, thus the nodes are being
+reused from AM62P includes instead of duplicating the definitions.
+
+Some highlights of J722S SoC (in addition to AM62P SoC features) are:
+
+* Two Cortex-R5F for Functional Safety or general-purpose usage and
+  two C7x floating point vector DSP with Matrix Multiply Accelerator
+  for deep learning.
+
+* Vision Processing Accelerator (VPAC) with image signal processor
+  and Depth and Motion Processing Accelerator (DMPAC).
+
+* 7xUARTs, 3xSPI, 5xI2C, 2xUSB2, 2xCAN-FD, 3xMMC and SD, GPMC for
+  NAND/FPGA connection, OSPI memory controller, 5xMcASP for audio,
+  4xCSI-RX for Camera, 1 PCIe Gen3 controller, USB3.0 eCAP/eQEP,
+  ePWM, among other peripherals.
+
+For those interested, more details about this SoC can be found in the
+Technical Reference Manual here: https://www.ti.com/lit/zip/sprujb3
+
+Boot Flow:
+----------
+
+The bootflow is exactly the same as all SoCs in the am62xxx extended SoC
+family. Below is the pictorial representation:
+
+.. image:: img/boot_diagram_k3_current.svg

+Debugging U-Boot with GDB
+=========================
+
+Using a JTAG adapter it is possible to debug a running U-Boot with GDB.
+A common way is to connect a debug adapter to the JTAG connector of your
+board, run a GDB server, connect GDB to the GDB server, and use GDB as usual.
+
+Similarly QEMU can provide a GDB server.
+
+Preparing build
+---------------
+
+Building U-Boot with with reduced optimization (-Og) and without link time
+optimization is recommended for easier debugging::
+
+    CONFIG_CC_OPTIMIZE_FOR_DEBUG=y
+    CONFIG_LTO=n
+
+Otherwise build, install, and run U-Boot as usual.
+
+Using OpenOCD as GDB server
+---------------------------
+
+`OpenOCD <https://openocd.org/>`_ is an open source tool supporting hardware
+debug probes, and providing a GDB server. It is readily available in major Linux
+distributions or you can build it from source.
+
+Here is example of starting OpenOCD on Debian using a J-Link adapter and a
+board with an AT91 SAMA5D2 SoC:
+
+.. code-block:: console
+
+    $ openocd -f interface/jlink.cfg -f target/at91sama5d2.cfg -c 'adapter speed 4000'
+    Open On-Chip Debugger 0.12.0
+    Licensed under GNU GPL v2
+    For bug reports, read
+            http://openocd.org/doc/doxygen/bugs.html
+    Info : auto-selecting first available session transport "jtag". To override use 'transport select <transport>'.
+    adapter speed: 4000 kHz
+
+    Info : Listening on port 6666 for tcl connections
+    Info : Listening on port 4444 for telnet connections
+    Info : J-Link V10 compiled Jan 30 2023 11:28:07
+    Info : Hardware version: 10.10
+    Info : VTarget = 3.244 V
+    Info : clock speed 4000 kHz
+    Info : JTAG tap: at91sama5d2.cpu tap/device found: 0x5ba00477 (mfg: 0x23b (ARM Ltd), part: 0xba00, ver: 0x5)

+    Info : at91sama5d2.cpu_a5.0: MPIDR level2 0, cluster 0, core 0, mono core, no SMT
+    Info : starting gdb server for at91sama5d2.cpu_a5.0 on 3333
+    Info : Listening on port 3333 for gdb connections
+
+Notice that OpenOCD is listening on port 3333 for GDB connections.
+
+Using QEMU as GDB server
+------------------------
+
+When running U-Boot on QEMU you can used the '-gdb' parameter to provide a
+GDB server:
+
+     qemu-system-riscv64 -M virt -nographic -gdb tcp::3333 -kernel u-boot
+
+Running a GDB session
+----------------------
+
+You need a GDB suited for your target. This can be the GDB coming with your
+toolchain or *gdb-multiarch* available in your Linux distribution.
+
+.. prompt:: bash $
+
+    gdb-multiarch u-boot
+
+In the above command-line *u-boot* is the U-boot binary in your build
+directory. You may need to adjust the path when calling GDB.
+
+Connect to the GDB server like this:
+
+.. code-block:: console
+
+    (gdb) target extended-remote :3333
+    Remote debugging using :3333
+    0x27fa9ac6 in ?? ()
+    (gdb)
+
+This is fine for debugging before U-Boot relocates itself.
+
+For debugging U-Boot after relocation you need to indicate the relocation
+address to GDB. You can retrieve the relocation address from the U-Boot shell
+with the command *bdinfo*:
+
+.. code-block:: console
+
+    U-Boot> bdinfo
+    boot_params = 0x20000100

+nios2        gp
+powerpc      r2
+riscv        gp
+sh           r13
+============ ========
+
+On these architecture the relocation address cat be determined by
+dereferencing the global data pointer stored in register, *r9* in the example:
+
+.. code-block:: console
+
+     (gdb) p/x (*(struct global_data*)$r9)->relocaddr
+     $1 = 0x27f7a000
+
+In the GDB shell discard the previously loaded symbol file and add it once
+again with the relocation address like this:
+
+.. code-block:: console
+
+    (gdb) symbol-file
+    Discard symbol table from `/home/adahl/build/u-boot/v2024.04.x/u-boot'? (y or n) y
+    No symbol file now.
+    (gdb) add-symbol-file u-boot 0x27f7a000
+    add symbol table from file "u-boot" at
+            .text_addr = 0x27f7a000
+    (y or n) y
+    Reading symbols from u-boot...
+    (gdb)
+
+You can now use GDB as usual, setting breakpoints, printing backtraces,
+inspecting variables, stepping through the code, etc.

+Porting Capsule Updates to new boards
+*************************************
+
+It is important, when using a reference board as a starting point for a custom
+board, that certain steps are taken to properly support Capsule Updates.
+
+Capsule GUIDs need to be unique for each firmware and board. That is, if two
+firmwares are built from the same source but result in different binaries
+because they are built for different boards, they should have different GUIDs.
+Therefore it is important when creating support for a new board, new GUIDs are
+defined in the board's header file.  *DO NOT* reuse capsule GUIDs.

-The entire script is available in doc/imx/habv4/csf_examples/mx8m/csf.sh
-and can be used as follows to modify flash.bin to be signed
-(adjust paths as needed):
+to authenticate, which keys to install, use and etc. The CSF is generated
+using the CST Code Signing Tool based on input configuration file. This tool
+input configuration file is generated using binman, and the tool is invoked
+from binman as well.
+
+The SPL and fitImage sections of the generated image are signed separately.
+The signing is activated by wrapping SPL and fitImage sections into nxp-imx8mcst
+etype, which is done automatically in arch/arm/dts/imx8m{m,n,p,q}-u-boot.dtsi
+in case CONFIG_IMX_HAB Kconfig symbol is enabled.
+
+Per default the HAB keys and certificates need to be located in the build
+directory, this means creating a symbolic link or copying the following files
+from the HAB keys directory flat (e.g. removing the `keys` and `cert`
+subdirectory) into the u-boot build directory for the CST Code Signing Tool to
+locate them:
+
+- `crts/SRK_1_2_3_4_table.bin`
+- `crts/CSF1_1_sha256_4096_65537_v3_usr_crt.pem`
+- `keys/CSF1_1_sha256_4096_65537_v3_usr_key.pem`
+- `crts/IMG1_1_sha256_4096_65537_v3_usr_crt.pem`
+- `keys/IMG1_1_sha256_4096_65537_v3_usr_key.pem`
+- `keys/key_pass.txt`
+
+The paths to the SRK table and the certificates can be modified via changes to
+the nxp_imx8mcst device tree node(s), however the other files are required by
+the CST tools as well, and will be searched for in relation to them.
+
+Build of flash.bin target then produces a signed flash.bin automatically.
+
+The nxp-imx8mcst etype is configurable using either DT properties or environment
+variables. The following DT properties and environment variables are supported.
+Note that environment variables override DT properties.
