-U-Boot on STMicroelectronics STM32MP15x
-=======================================
-
-1. Summary
-==========
-This is a quick instruction for setup stm32mp1 boards.
-
-2. Supported devices
-====================
-U-Boot supports STMP32MP15x SoCs: STM32MP157, STM32MP153 and STM32MP151
-
-The STM32MP15x is a Cortex-A MPU aimed at various applications.
-It features:
-- Dual core Cortex-A7 application core (Single on STM32MP151)
-- 2D/3D image composition with GPU (only on STM32MP157)
-- Standard memories interface support
-- Standard connectivity, widely inherited from the STM32 MCU family
-- Comprehensive security support
-
-Everything is supported in Linux but U-Boot is limited to:
-1. UART
-2. SDCard/MMC controller (SDMMC)
-3. NAND controller (FMC)
-4. NOR controller (QSPI)
-5. USB controller (OTG DWC2)
-6. Ethernet controller
-
-And the necessary drivers
-1. I2C
-2. STPMIC1 (PMIC and regulator)
-3. Clock, Reset, Sysreset
-4. Fuse
-
-Currently the following boards are supported:
-+ stm32mp157a-avenger96.dts
-+ stm32mp157a-dk1.dts
-+ stm32mp157c-dk2.dts
-+ stm32mp157c-ed1.dts
-+ stm32mp157c-ev1.dts
-
-3. Boot Sequences
-=================
-
-BootRom => FSBL in SYSRAM => SSBL in DDR => OS (Linux Kernel)
-
-with FSBL = First Stage Bootloader
- SSBL = Second Stage Bootloader
-
-3 boot configurations are supported:
-
-1) The "Trusted" boot chain (defconfig_file : stm32mp15_trusted_defconfig)
- BootRom => FSBL = Trusted Firmware-A (TF-A) => SSBL = U-Boot
- TF-A performs a full initialization of Secure peripherals and installs a
- secure monitor.
- U-Boot is running in normal world and uses TF-A monitor
- to access to secure resources.
-
-2) The "Trusted" boot chain with OP-TEE
- (defconfig_file : stm32mp15_optee_defconfig)
- BootRom => FSBL = Trusted Firmware-A (TF-A) => SSBL = U-Boot
- TF-A performs a full initialization of Secure peripherals and installs OP-TEE
- from specific partitions (teeh, teed, teex).
- U-Boot is running in normal world and uses OP-TEE monitor to access
- to secure resources.
-
-3) The "Basic" boot chain (defconfig_file : stm32mp15_basic_defconfig)
- BootRom => FSBL = U-Boot SPL => SSBL = U-Boot
- SPL has limited security initialisation
- U-Boot is running in secure mode and provide a secure monitor to the kernel
- with only PSCI support (Power State Coordination Interface defined by ARM).
-
-All the STM32MP15x boards supported by U-Boot use the same generic board
-stm32mp1 which support all the bootable devices.
-
-Each board is configurated only with the associated device tree.
-
-4. Device Tree Selection
-========================
-
-You need to select the appropriate device tree for your board,
-the supported device trees for stm32mp157 are:
-
-+ ev1: eval board with pmic stpmic1 (ev1 = mother board + daughter ed1)
- dts: stm32mp157c-ev1
-
-+ ed1: daughter board with pmic stpmic1
- dts: stm32mp157c-ed1
-
-+ dk1: Discovery board
- dts: stm32mp157a-dk1
-
-+ dk2: Discovery board = dk1 with a BT/WiFI combo and a DSI panel
- dts: stm32mp157c-dk2
-
-+ avenger96: Avenger96 board from Arrow Electronics
- dts: stm32mp157a-avenger96
-
-5. Build Procedure
-==================
-
-1. Install 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)
-
-2. Set the cross compiler:
-
- # export CROSS_COMPILE=/path/to/toolchain/arm-linux-gnueabi-
- (you can use any gcc cross compiler compatible with U-Boot)
-
-3. Select the output directory (optional)
-
- # export KBUILD_OUTPUT=/path/to/output
-
- for example: use one output directory for each configuration
- # export KBUILD_OUTPUT=stm32mp15_trusted
- # export KBUILD_OUTPUT=stm32mp15_optee
- # export KBUILD_OUTPUT=stm32mp15_basic
-
- you can build outside of code directory:
- # export KBUILD_OUTPUT=../build/stm32mp15_trusted
-
-4. Configure U-Boot:
-
- # make <defconfig_file>
-
- - For trusted boot mode : "stm32mp15_trusted_defconfig"
- - For trusted with OP-TEE boot mode : "stm32mp15_optee_defconfig"
- - For basic boot mode: "stm32mp15_basic_defconfig"
-
-5. Configure the device-tree and build the U-Boot image:
-
- # make DEVICE_TREE=<name> all
-
- example:
- a) trusted boot on ev1
- # export KBUILD_OUTPUT=stm32mp15_trusted
- # make stm32mp15_trusted_defconfig
- # make DEVICE_TREE=stm32mp157c-ev1 all
-
- b) trusted with OP-TEE boot on dk2
- # export KBUILD_OUTPUT=stm32mp15_optee
- # make stm32mp15_optee_defconfig
- # make DEVICE_TREE=stm32mp157c-dk2 all
-
- c) basic boot on ev1
- # export KBUILD_OUTPUT=stm32mp15_basic
- # make stm32mp15_basic_defconfig
- # make DEVICE_TREE=stm32mp157c-ev1 all
-
- d) basic boot on ed1
- # export KBUILD_OUTPUT=stm32mp15_basic
- # make stm32mp15_basic_defconfig
- # make DEVICE_TREE=stm32mp157c-ed1 all
-
- e) basic boot on dk1
- # export KBUILD_OUTPUT=stm32mp15_basic
- # make stm32mp15_basic_defconfig
- # make DEVICE_TREE=stm32mp157a-dk1 all
-
- f) basic boot on avenger96
- # export KBUILD_OUTPUT=stm32mp15_basic
- # make stm32mp15_basic_defconfig
- # make DEVICE_TREE=stm32mp157a-avenger96 all
-
-6. Output files
-
- BootRom and TF-A expect binaries with STM32 image header
- SPL expects file with U-Boot uImage header
-
- So in the output directory (selected by KBUILD_OUTPUT),
- you can found the needed files:
-
- a) For Trusted boot (with or without OP-TEE)
- + FSBL = tf-a.stm32 (provided by TF-A compilation)
- + SSBL = u-boot.stm32
-
- b) For Basic boot
- + FSBL = spl/u-boot-spl.stm32
- + SSBL = u-boot.img
-
-6. Switch Setting for Boot Mode
-===============================
-
-You can select the boot mode, on the board with one switch :
-
-- on the daugther board ed1 with the switch SW1 : BOOT0, BOOT1, BOOT2
-
- -----------------------------------
- Boot Mode BOOT2 BOOT1 BOOT0
- -----------------------------------
- Reserved 0 0 0
- NOR 0 0 1
- SD-Card 1 0 1
- eMMC 0 1 0
- NAND 0 1 1
- Recovery 1 1 0
- Recovery 0 0 0
-
-- on board DK1/DK2 with the switch SW1 : BOOT0, BOOT2
- (BOOT1 forced to 0, NOR not supported)
-
- --------------------------
- Boot Mode BOOT2 BOOT0
- --------------------------
- Reserved 1 0
- SD-Card 1 1
- Recovery 0 0
-
-- Boot mode of Avenger96 can be selected using switch S3
-
- -----------------------------------
- Boot Mode BOOT2 BOOT1 BOOT0
- -----------------------------------
- Recovery 0 0 0
- NOR 0 0 1
- SD-Card 1 0 1
- eMMC 0 1 0
- NAND 0 1 1
- Reserved 1 0 0
- Recovery 1 1 0
- SD-Card 1 1 1
-
-Recovery is a boot from serial link (UART/USB) and it is used with
-STM32CubeProgrammer tool to load executable in RAM and to update the flash
-devices available on the board (NOR/NAND/eMMC/SDCARD).
-The communication between HOST and board is based on
-- for UARTs : the uart protocol used with all MCU STM32
-- for USB : based on USB DFU 1.1 (without the ST extensions used on MCU STM32)
-
-7. Prepare an SDCard
-===================
-
-The minimal requirements for STMP32MP1 boot up to U-Boot are:
-- GPT partitioning (with gdisk or with sgdisk)
-- 2 fsbl partitions, named fsbl1 and fsbl2, size at least 256KiB
-- one ssbl partition for U-Boot
-
-Then the minimal GPT partition is:
- ----- ------- --------- --------------
- | Num | Name | Size | Content |
- ----- ------- -------- ---------------
- | 1 | fsbl1 | 256 KiB | TF-A or SPL |
- | 2 | fsbl2 | 256 KiB | TF-A or SPL |
- | 3 | ssbl | enought | U-Boot |
- | * | - | - | Boot/Rootfs |
- ----- ------- --------- --------------
-
-(*) add bootable partition for extlinux.conf
- following Generic Distribution
- (doc/README.distro for use)
-
- according the used card reader select the block device
- (/dev/sdx or /dev/mmcblk0)
- in the next example I use /dev/mmcblk0
-
-for example: with gpt table with 128 entries
-
- a) remove previous formatting
- # sgdisk -o /dev/<SDCard dev>
-
- b) create minimal image
- # sgdisk --resize-table=128 -a 1 \
- -n 1:34:545 -c 1:fsbl1 \
- -n 2:546:1057 -c 2:fsbl2 \
- -n 3:1058:5153 -c 3:ssbl \
- -p /dev/<SDCard dev>
-
- you can add other partitions for kernel
- one partition rootfs for example:
- -n 4:5154: -c 4:rootfs \
-
- c) copy the FSBL (2 times) and SSBL file on the correct partition.
- in this example in partition 1 to 3
-
- for basic boot mode : <SDCard dev> = /dev/mmcblk0
- # dd if=u-boot-spl.stm32 of=/dev/mmcblk0p1
- # dd if=u-boot-spl.stm32 of=/dev/mmcblk0p2
- # dd if=u-boot.img of=/dev/mmcblk0p3
-
- for trusted boot mode :
- # dd if=tf-a.stm32 of=/dev/mmcblk0p1
- # dd if=tf-a.stm32 of=/dev/mmcblk0p2
- # dd if=u-boot.stm32 of=/dev/mmcblk0p3
-
-To boot from SDCard, select BootPinMode = 1 0 1 and reset.
-
-8. Prepare eMMC
-===============
-You can use U-Boot to copy binary in eMMC.
-
-In the next example, you need to boot from SDCARD and the images (u-boot-spl.stm32, u-boot.img)
-are presents on SDCARD (mmc 0) in ext4 partition 4 (bootfs).
-
-To boot from SDCard, select BootPinMode = 1 0 1 and reset.
-
-Then you update the eMMC with the next U-Boot command :
-
-a) prepare GPT on eMMC,
- example with 2 partitions, bootfs and roots:
-
- # setenv emmc_part "name=ssbl,size=2MiB;name=bootfs,type=linux,bootable,size=64MiB;name=rootfs,type=linux,size=512"
- # gpt write mmc 1 ${emmc_part}
-
-b) copy SPL on eMMC on firts boot partition
- (SPL max size is 256kB, with LBA 512, 0x200)
-
- # ext4load mmc 0:4 0xC0000000 u-boot-spl.stm32
- # mmc dev 1
- # mmc partconf 1 1 1 1
- # mmc write ${fileaddr} 0 200
- # mmc partconf 1 1 1 0
-
-c) copy U-Boot in first GPT partition of eMMC
-
- # ext4load mmc 0:4 0xC0000000 u-boot.img
- # mmc dev 1
- # part start mmc 1 1 partstart
- # mmc write ${fileaddr} ${partstart} ${filesize}
-
-To boot from eMMC, select BootPinMode = 0 1 0 and reset.
-
-9. MAC Address
-==============
-
-Please read doc/README.enetaddr for the implementation guidelines for mac id
-usage. Basically, environment has precedence over board specific storage.
-
-For STMicroelectonics board, it is retrieved in STM32MP15x otp :
-- OTP_57[31:0] = MAC_ADDR[31:0]
-- OTP_58[15:0] = MAC_ADDR[47:32]
-
-To program a MAC address on virgin OTP words above, you can use the fuse command
-on bank 0 to access to internal OTP:
-
- Prerequisite: check if a MAC address isn't yet programmed in OTP
-
- 1- check OTP: their value must be equal to 0
-
- STM32MP> fuse sense 0 57 2
- Sensing bank 0:
- Word 0x00000039: 00000000 00000000
-
- 2- check environment variable
-
- STM32MP> env print ethaddr
- ## Error: "ethaddr" not defined
-
- Example to set mac address "12:34:56:78:9a:bc"
-
- 1- Write OTP
- STM32MP> fuse prog -y 0 57 0x78563412 0x0000bc9a
-
- 2- Read OTP
- STM32MP> fuse sense 0 57 2
- Sensing bank 0:
- Word 0x00000039: 78563412 0000bc9a
-
- 3- next REBOOT :
- ### Setting environment from OTP MAC address = "12:34:56:78:9a:bc"
-
- 4 check env update
- STM32MP> env print ethaddr
- ethaddr=12:34:56:78:9a:bc
-
-warning:: This MAC address provisioning can't be executed twice on the same
- board as the OTP are protected. It is already done for the board
- provided by STMicroelectronics.
-
-10. Coprocessor firmware
-========================
-
-U-Boot can boot the coprocessor before the kernel (coprocessor early boot).
-
-A/ Manuallly by using rproc commands (update the bootcmd)
- Configurations
- # env set name_copro "rproc-m4-fw.elf"
- # env set dev_copro 0
- # env set loadaddr_copro 0xC1000000
-
- Load binary from bootfs partition (number 4) on SDCard (mmc 0)
- # ext4load mmc 0:4 ${loadaddr_copro} ${name_copro}
- => ${filesize} updated with the size of the loaded file
-
- Start M4 firmware with remote proc command
- # rproc init
- # rproc load ${dev_copro} ${loadaddr_copro} ${filesize}
- # rproc start ${dev_copro}
-
-B/ Automatically by using FIT feature and generic DISTRO bootcmd
-
- see examples in this directory :
-
- Generate FIT including kernel + device tree + M4 firmware
- with cfg with M4 boot
- $> mkimage -f fit_copro_kernel_dtb.its fit_copro_kernel_dtb.itb
-
- Then using DISTRO configuration file: see extlinux.conf to select
- the correct configuration
- => stm32mp157c-ev1-m4
- => stm32mp157c-dk2-m4
-
-11. DFU support
-===============
-
-The DFU is supported on ST board.
-The env variable dfu_alt_info is automatically build, and all
-the memory present on the ST boards are exported.
-
-The mode is started by
-
-STM32MP> dfu 0
-
-On EV1 board:
-
-STM32MP> dfu 0 list
-

+STM32MP15x boards
+=================
+
+This is a quick instruction for setup STM32MP15x boards.
+
+Supported devices
+-----------------
+
+U-Boot supports STMP32MP15x SoCs:
+
+ - STM32MP157
+ - STM32MP153
+ - STM32MP151
+
+The STM32MP15x is a Cortex-A MPU aimed at various applications.
+
+It features:
+
+ - Dual core Cortex-A7 application core (Single on STM32MP151)
+ - 2D/3D image composition with GPU (only on STM32MP157)
+ - Standard memories interface support
+ - Standard connectivity, widely inherited from the STM32 MCU family
+ - Comprehensive security support
+
+Everything is supported in Linux but U-Boot is limited to:
+
+ 1. UART
+ 2. SD card/MMC controller (SDMMC)
+ 3. NAND controller (FMC)
+ 4. NOR controller (QSPI)
+ 5. USB controller (OTG DWC2)
+ 6. Ethernet controller
+
+And the necessary drivers
+
+ 1. I2C
+ 2. STPMIC1 (PMIC and regulator)
+ 3. Clock, Reset, Sysreset
+ 4. Fuse
+
+Currently the following boards are supported:
+
+ + stm32mp157a-avenger96.dts
+ + stm32mp157a-dk1.dts
+ + stm32mp157c-dk2.dts
+ + stm32mp157c-ed1.dts
+ + stm32mp157c-ev1.dts
+
+Boot Sequences
+--------------
+
+3 boot configurations are supported with:
+
++----------+------------------------+-------------------------+--------------+
+| **ROM** | **FSBL** | **SSBL** | **OS** |
++ **code** +------------------------+-------------------------+--------------+
+| | First Stage Bootloader | Second Stage Bootloader | Linux Kernel |
++ +------------------------+-------------------------+--------------+
+| | embedded RAM | DDR |
++----------+------------------------+-------------------------+--------------+
+
+The **Trusted** boot chain

+ +-------------+-------------------------+------------+-------+
+
+TF-A performs a full initialization of Secure peripherals and installs a
+secure monitor (BL32=SPMin).
+
+U-Boot is running in normal world and uses TF-A monitor to access
+to secure resources.
+
+The **Trusted** boot chain with **OP-TEE**

+ | |Trusted Firmware-A (TF-A)| U-Boot | Linux |
+ +-------------+-------------------------+------------+-------+
+ | TrustZone |OP-TEE |
+ +-------------+-------------------------+------------+-------+
+
+TF-A performs a full initialization of Secure peripherals and installs OP-TEE
+from specific partitions (teeh, teed, teex).
+
+U-Boot is running in normal world and uses OP-TEE monitor to access
+to secure resources.
+
+The **Basic** boot chain
+````````````````````````
+
+defconfig_file : stm32mp15_basic_defconfig
+
+ +-------------+------------+------------+-------+
+ | ROM code | FSBL | SSBL | OS |
+ + +------------+------------+-------+
+ | |U-Boot SPL | U-Boot | Linux |
+ +-------------+------------+------------+-------+
+ | TrustZone | | PSCI from U-Boot |
+ +-------------+------------+------------+-------+
+
+SPL has limited security initialization
+
+U-Boot is running in secure mode and provide a secure monitor to the kernel
+with only PSCI support (Power State Coordination Interface defined by ARM).
+
+All the STM32MP15x boards supported by U-Boot use the same generic board
+stm32mp1 which support all the bootable devices.
+
+Each board is configured only with the associated device tree.
+
+Device Tree Selection
+---------------------
+
+You need to select the appropriate device tree for your board,
+the supported device trees for STM32MP15x are:
+
++ ev1: eval board with pmic stpmic1 (ev1 = mother board + daughter ed1)
+
+ + stm32mp157c-ev1
+
++ ed1: daughter board with pmic stpmic1
+
+ + stm32mp157c-ed1
+
++ dk1: Discovery board
+
+ + stm32mp157a-dk1
+
++ dk2: Discovery board = dk1 with a BT/WiFI combo and a DSI panel
+
+ + stm32mp157c-dk2
+
++ avenger96: Avenger96 board from Arrow Electronics
+
+ + stm32mp157a-avenger96
+
+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=stm32mp15_trusted
+ # export KBUILD_OUTPUT=stm32mp15_optee
+ # export KBUILD_OUTPUT=stm32mp15_basic
+
+ you can build outside of code directory::
+
+ # export KBUILD_OUTPUT=../build/stm32mp15_trusted
+
+4. Configure U-Boot::
+
+ # make <defconfig_file>
+
+ with <defconfig_file>:
+
+ - For **trusted** boot mode : **stm32mp15_trusted_defconfig**
+ - For **trusted** with OP-TEE boot mode : **stm32mp15_optee_defconfig**
+ - For basic boot mode: stm32mp15_basic_defconfig
+
+5. Configure the device-tree and build the U-Boot image::
+
+ # make DEVICE_TREE=<name> all
+
+ Examples:
+
+ a) trusted boot on ev1::
+
+ # export KBUILD_OUTPUT=stm32mp15_trusted
+ # make stm32mp15_trusted_defconfig
+ # make DEVICE_TREE=stm32mp157c-ev1 all
+
+ b) trusted with OP-TEE boot on dk2::
+
+ # export KBUILD_OUTPUT=stm32mp15_optee
+ # make stm32mp15_optee_defconfig
+ # make DEVICE_TREE=stm32mp157c-dk2 all
+
+ c) basic boot on ev1::
+
+ # export KBUILD_OUTPUT=stm32mp15_basic
+ # make stm32mp15_basic_defconfig
+ # make DEVICE_TREE=stm32mp157c-ev1 all
+
+ d) basic boot on ed1::
+
+ # export KBUILD_OUTPUT=stm32mp15_basic
+ # make stm32mp15_basic_defconfig
+ # make DEVICE_TREE=stm32mp157c-ed1 all
+
+ e) basic boot on dk1::
+
+ # export KBUILD_OUTPUT=stm32mp15_basic
+ # make stm32mp15_basic_defconfig
+ # make DEVICE_TREE=stm32mp157a-dk1 all
+
+ f) basic boot on avenger96::
+
+ # export KBUILD_OUTPUT=stm32mp15_basic
+ # make stm32mp15_basic_defconfig
+ # make DEVICE_TREE=stm32mp157a-avenger96 all
+
+6. Output files
+
+ BootRom and TF-A expect binaries with STM32 image header
+ SPL expects file with U-Boot uImage header
+
+ So in the output directory (selected by KBUILD_OUTPUT),
+ you can found the needed files:
+
+ - For **Trusted** boot (with or without OP-TEE)
+
+ - FSBL = **tf-a.stm32** (provided by TF-A compilation)
+ - SSBL = **u-boot.stm32**
+
+ - For Basic boot
+
+ - FSBL = spl/u-boot-spl.stm32
+ - SSBL = u-boot.img
+
+Switch Setting for Boot Mode
+----------------------------
+
+You can select the boot mode, on the board with one switch, to select
+the boot pin values = BOOT0, BOOT1, BOOT2
+
+ +-------------+---------+---------+---------+
+ |*Boot Mode* | *BOOT2* | *BOOT1* | *BOOT0* |
+ +=============+=========+=========+=========+
+ | Recovery | 0 | 0 | 0 |
+ +-------------+---------+---------+---------+
+ | NOR | 0 | 0 | 1 |
+ +-------------+---------+---------+---------+
+ | eMMC | 0 | 1 | 0 |
+ +-------------+---------+---------+---------+
+ | NAND | 0 | 1 | 1 |
+ +-------------+---------+---------+---------+
+ | Reserved | 1 | 0 | 0 |
+ +-------------+---------+---------+---------+
+ | SD-Card | 1 | 0 | 1 |
+ +-------------+---------+---------+---------+
+ | Recovery | 1 | 1 | 0 |
+ +-------------+---------+---------+---------+
+ | SPI-NAND | 1 | 1 | 1 |
+ +-------------+---------+---------+---------+
+
+- on the **daugther board ed1 = MB1263** with the switch SW1
+- on **Avenger96** with switch S3 (NOR and SPI-NAND are not applicable)
+- on board **DK1/DK2** with the switch SW1 = BOOT0, BOOT2
+ with only 2 pins available (BOOT1 is forced to 0 and NOR not supported),
+ the possible value becomes:
+
+ +-------------+---------+---------+
+ |*Boot Mode* | *BOOT2* | *BOOT0* |
+ +=============+=========+=========+
+ | Recovery | 0 | 0 |
+ +-------------+---------+---------+
+ | NOR (NA)| 0 | 1 |
+ +-------------+---------+---------+
+ | Reserved | 1 | 0 |
+ +-------------+---------+---------+
+ | SD-Card | 1 | 1 |
+ +-------------+---------+---------+
+
+Recovery is a boot from serial link (UART/USB) and it is used with
+STM32CubeProgrammer tool to load executable in RAM and to update the flash
+devices available on the board (NOR/NAND/eMMC/SD card).
+
+The communication between HOST and board is based on
+
+ - for UARTs : the uart protocol used with all MCU STM32
+ - for USB : based on USB DFU 1.1 (without the ST extensions used on MCU STM32)
+
+Prepare an SD card
+------------------
+
+The minimal requirements for STMP32MP15x boot up to U-Boot are:
+
+- GPT partitioning (with gdisk or with sgdisk)
+- 2 fsbl partitions, named fsbl1 and fsbl2, size at least 256KiB
+- one ssbl partition for U-Boot
+
+Then the minimal GPT partition is:
+
+ +-------+--------+---------+-------------+
+ | *Num* | *Name* | *Size* | *Content* |
+ +=======+========+=========+=============+
+ | 1 | fsbl1 | 256 KiB | TF-A or SPL |
+ +-------+--------+---------+-------------+
+ | 2 | fsbl2 | 256 KiB | TF-A or SPL |
+ +-------+--------+---------+-------------+
+ | 3 | ssbl | enought | U-Boot |
+ +-------+--------+---------+-------------+
+ | 4 | <any> | <any> | Rootfs |
+ +-------+--------+---------+-------------+
+
+Add a 4th partition (Rootfs) marked bootable with a file extlinux.conf
+following the Generic Distribution feature (doc/README.distro for use).
+
+According the used card reader select the correct block device
+(for example /dev/sdx or /dev/mmcblk0).
+
+In the next example, it is /dev/mmcblk0
+
+For example: with gpt table with 128 entries
+
+a) remove previous formatting::
+
+ # sgdisk -o /dev/<SD card dev>
+
+b) create minimal image::
+
+ # sgdisk --resize-table=128 -a 1 \
+ -n 1:34:545 -c 1:fsbl1 \
+ -n 2:546:1057 -c 2:fsbl2 \
+ -n 3:1058:5153 -c 3:ssbl \
+ -n 4:5154: -c 4:rootfs \
+ -p /dev/<SD card dev>
+
+ With other partition for kernel one partition rootfs for kernel.
+
+c) copy the FSBL (2 times) and SSBL file on the correct partition.
+ in this example in partition 1 to 3
+
+ for basic boot mode : <SD card dev> = /dev/mmcblk0::
+
+ # dd if=u-boot-spl.stm32 of=/dev/mmcblk0p1
+ # dd if=u-boot-spl.stm32 of=/dev/mmcblk0p2
+ # dd if=u-boot.img of=/dev/mmcblk0p3
+
+ for trusted boot mode: ::
+
+ # dd if=tf-a.stm32 of=/dev/mmcblk0p1
+ # dd if=tf-a.stm32 of=/dev/mmcblk0p2
+ # dd if=u-boot.stm32 of=/dev/mmcblk0p3
+
+To boot from SD card, select BootPinMode = 1 0 1 and reset.
+
+Prepare eMMC
+------------
+
+You can use U-Boot to copy binary in eMMC.
+
+In the next example, you need to boot from SD card and the images
+(u-boot-spl.stm32, u-boot.img) are presents on SD card (mmc 0)
+in ext4 partition 4 (bootfs).
+
+To boot from SD card, select BootPinMode = 1 0 1 and reset.
+
+Then you update the eMMC with the next U-Boot command :
+
+a) prepare GPT on eMMC,
+ example with 2 partitions, bootfs and roots::
+
+ # setenv emmc_part "name=ssbl,size=2MiB;name=bootfs,type=linux,bootable,size=64MiB;name=rootfs,type=linux,size=512"
+ # gpt write mmc 1 ${emmc_part}
+
+b) copy SPL on eMMC on firts boot partition
+ (SPL max size is 256kB, with LBA 512, 0x200)::
+
+ # ext4load mmc 0:4 0xC0000000 u-boot-spl.stm32
+ # mmc dev 1
+ # mmc partconf 1 1 1 1
+ # mmc write ${fileaddr} 0 200
+ # mmc partconf 1 1 1 0
+
+c) copy U-Boot in first GPT partition of eMMC::
+
+ # ext4load mmc 0:4 0xC0000000 u-boo t.img
+ # mmc dev 1
+ # part start mmc 1 1 partstart
+ # mmc write ${fileaddr} ${partstart} ${filesize}
+
+To boot from eMMC, select BootPinMode = 0 1 0 and reset.
+
+MAC Address
+-----------
+
+Please read doc/README.enetaddr for the implementation guidelines for mac id
+usage. Basically, environment has precedence over board specific storage.
+
+For STMicroelectonics board, it is retrieved in STM32MP15x OTP :
+
+ - OTP_57[31:0] = MAC_ADDR[31:0]
+ - OTP_58[15:0] = MAC_ADDR[47:32]
+
+To program a MAC address on virgin OTP words above, you can use the fuse command
+on bank 0 to access to internal OTP:
+
+Prerequisite: check if a MAC address isn't yet programmed in OTP
+
+1) check OTP: their value must be equal to 0
+
+ STM32MP> fuse sense 0 57 2
+ Sensing bank 0:
+ Word 0x00000039: 00000000 00000000
+
+2) check environment variable
+
+ STM32MP> env print ethaddr
+ ## Error: "ethaddr" not defined
+
+Example to set mac address "12:34:56:78:9a:bc"
+
+1) Write OTP::
+
+ STM32MP> fuse prog -y 0 57 0x78563412 0x0000bc9a
+
+2) Read OTP::
+
+ STM32MP> fuse sense 0 57 2
+ Sensing bank 0:
+ Word 0x00000039: 78563412 0000bc9a
+
+3) next REBOOT, in the trace::
+
+ ### Setting environment from OTP MAC address = "12:34:56:78:9a:bc"
+
+4) check env update::
+
+ STM32MP> env print ethaddr
+ ethaddr=12:34:56:78:9a:bc
+
+.. warning:: This command can't be executed twice on the same board as
+ OTP are protected. It is already done for the board
+ provided by STMicroelectronics.
+
+Coprocessor firmware
+--------------------
+
+U-Boot can boot the coprocessor before the kernel (coprocessor early boot).
+
+a) Manuallly by using rproc commands (update the bootcmd)
+
+ Configurations::
+
+ # env set name_copro "rproc-m4-fw.elf"
+ # env set dev_copro 0
+ # env set loadaddr_copro 0xC1000000
+
+ Load binary from bootfs partition (number 4) on SD card (mmc 0)::
+
+ # ext4load mmc 0:4 ${loadaddr_copro} ${name_copro}
+
+ => ${filesize} variable is updated with the size of the loaded file.
+
+ Start M4 firmware with remote proc command::
+
+ # rproc init
+ # rproc load ${dev_copro} ${loadaddr_copro} ${filesize}
+ # rproc start ${dev_copro}"00270033
+
+b) Automatically by using FIT feature and generic DISTRO bootcmd
+
+ see examples in the board stm32mp1 directory: fit_copro_kernel_dtb.its
+
+ Generate FIT including kernel + device tree + M4 firmware with cfg with M4 boot::
+
+ $> mkimage -f fit_copro_kernel_dtb.its fit_copro_kernel_dtb.itb
+
+ Then using DISTRO configuration file: see extlinux.conf to select the correct
+ configuration:
+
+ - stm32mp157c-ev1-m4
+ - stm32mp157c-dk2-m4
+
+DFU support
+-----------
+
+The DFU is supported on ST board.
+
+The env variable dfu_alt_info is automatically build, and all
+the memory present on the ST boards are exported.
+
+The dfu mode is started by the command::
+
+ STM32MP> dfu 0
+
+On EV1 board, booting from SD card, without OP-TEE::
+
+ STM32MP> dfu 0 list
+ DFU alt settings list:
