Merge tag 'u-boot-stm32-20220510' of https://source.denx.de/u-boot/custodians/u-boot-stmWIP/10May2022

Add new STM32 MCU boards and Documentation
STM32 programmer improvements
video: support several LTDC HW versions and fix data enable polarity
board: fix stboard error message, consider USB cable connected when boot device is USB
configs: stm32mp1: set console variable for extlinux.conf
configs: stm32mp1: add support for baudrate higher than 115200 for ST-Link
ARM: stm32mp: Fix Silicon version handling and ft_system_setup()
phy: stm32-usbphyc: Add DT phy tuning support
arm: dts: stm32mp15: alignment with v5.18
ram: Conditionally enable ASR
mach-stm32mp: psci: retain MCUDIVR, PLL3CR, PLL4CR, MSSCKSELR across suspend
configs: Use TFTP_TSIZE on DHSOM and STMicroelectronics boards
ARM: stm32: Use default CONFIG_TFTP_BLOCKSIZE on DHSOM
pinctrl: stm32: rework GPIO holes management

++-----------+-------+
+
+Build Procedure
+---------------
+
+1. Install the required tools for U-Boot
+
+   * install package needed in U-Boot makefile
+     (libssl-dev, swig, libpython-dev...)
+
+   * install ARMv7 toolchain for 32bit Cortex-A (from Linaro,
+     from SDK for STM32MP15x, or any crosstoolchains from your distribution)
+     (you can use any gcc cross compiler compatible with U-Boot)
+
+2. Set the cross compiler::
+
+   # export CROSS_COMPILE=/path/to/toolchain/arm-linux-gnueabi-
+
+3. Select the output directory (optional)::
+
+   # export KBUILD_OUTPUT=/path/to/output
+
+   for example: use one output directory for each configuration::
+
+   # export KBUILD_OUTPUT=stm32f4
+   # export KBUILD_OUTPUT=stm32f7
+   # export KBUILD_OUTPUT=stm32h7
+
+   you can build outside of code directory::
+
+   # export KBUILD_OUTPUT=../build/stm32f4
+
+4. Configure U-Boot::
+
+   # make <defconfig_file>
+
+   For example with <defconfig_file>:
+
+   - For **stm32f429 discovery** board : **stm32f429-discovery_defconfig**
+   - For **stm32f769 discovery** board with SPL: **stm32f769-disco_spl_defconfig**
+   - For **stm32f769 discovery** board without SPL: **stm32f769-disco_defconfig**
+
+5. Configure the device-tree and build the U-Boot image::
+
+   # make DEVICE_TREE=<name> all
+
+   Examples:
+
+  a) boot with SPL on stm32f746 discovery board::
+
+     # export KBUILD_OUTPUT=stm32f746-disco
+     # make stm32f746-disco_spl_defconfig
+     # make all
+
+  b) boot without SPL on stm32f746 discovery board::
+
+     # export KBUILD_OUTPUT=stm32f746-disco
+     # make stm32f746-disco_defconfig
+     # make all
+
+  c) boot on stm32h743 discovery board::
+
+     # export KBUILD_OUTPUT=stm32h743-disco
+     # make stm32h743-disco_defconfig
+     # make all
+
+  d) boot on stm32h743 evaluation board::
+
+     # export KBUILD_OUTPUT=stm32h743-disco
+     # make stm32h743-eval_defconfig
+     # make all
+
+6. U-Boot Output files
+
+   So in the output directory (selected by KBUILD_OUTPUT),
+   you can found the needed U-Boot files, for example::
+
+     - stm32f746-disco_defconfig = **u-boot-dtb.bin** and **u-boot.dtb**
+
+       - FSBL = u-boot-dtb.bin
+
+     - stm32f746-disco_spl_defconfig = **u-boot-dtb.bin**, **u-boot.dtb** and **u-boot-with-spl.bin**
+
+       - FSBL + SSBL = u-boot-with-spl.bin
+       - SSBL = u-boot-dtb.bin
+
+7. Flash U-Boot files
+
+Plug STM32 MCUs board using the USB ST-Link connector, hence it will expose
+the flash area as a mass-storage. In this mass-storage you will find the
+following files:
+
+- DETAILS.TXT: give the bootrom version and build
+- MBED.HTM: shortcul to the hardware board description web page from st.com.
+
+Copy/paste the u-boot.bin or u-boot-with-spl.bin (in case of bootchain with SPL)
+to this mass-storage. The "COM" LED will blink alternatively red and green during
+the flash process. When done the board will reboot automatically.
+
+In case of boot with SPL, by default SPL will try to load either a Linux
+kernel (falcon mode) or, if the key "c" is maintained pressed, the main U-Boot.
