+Compilation of U-Boot:
+1. Pre-requisite
+2. Initialise cross-compilation via SDK
+3. Prepare U-Boot source code
+4. Management of U-Boot source code
+5. Compile U-Boot source code
+6. Update software on board
+
+1. Pre-requisite:
+-----------------
+OpenSTLinux SDK must be installed.
+
+For U-Boot build you need to install:
+* libncurses and libncursesw dev package
+    - Ubuntu: sudo apt-get install libncurses5-dev libncursesw5-dev
+    - Fedora: sudo yum install ncurses-devel
+* git:
+    - Ubuntu: sudo apt-get install git-core gitk
+    - Fedora: sudo yum install git
+
+If you have never configured you git configuration:
+    $> git config --global user.name "your_name"
+    $> git config --global user.email "your_email@example.com"
+
+2. Initialise cross-compilation via SDK:
+---------------------------------------
+* Source SDK environment:
+    $> source <path to SDK>/environment-setup-cortexa9hf-neon-openstlinux_weston-linux-gnueabi
+
+* To verify if you cross-compilation environment are put in place:
+    $> set | grep CROSS
+    CROSS_COMPILE=arm-openstlinux_weston-linux-gnueabi-
+
+Warning: the environment are valid only on the shell session where you have
+         sourced the sdk environment.
+
+3. Prepare U-Boot source:
+------------------------
+If you have the tarball and the list of patch then you must extract the
+tarball and apply the patch.
+    $> tar xfz <U-Boot source>.tar.gz
+    or
+    $> tar xfj <U-Boot source>.tar.bz2
+    or
+    $> tar xfJ <U-Boot source>.tar.xz
+    $> cd <directory to U-Boot source code>
+
+NB: if there is no git management on source code and you would like to have a
+git management on the code see section 4 [Management of U-Boot source code]
+    if there is some patch, please apply it on source code
+    $> for p in `ls -1 <path to patch>/*.patch`; do patch -p1 < $p; done
+
+4. Management of U-Boot source code:
+-----------------------------------
+If you like to have a better management of change made on U-Boot source, you
+can use git:
+    $> tar xfz <U-Boot source>.tar.gz
+    $> cd <directory of U-Boot source code>
+    $> test -d .git || git init . && git add . && git commit -m "U-Boot source code" && git gc
+    $> git checkout -b WORKING
+    $> for p in `ls -1 <path to patch>/*.patch`; do git am $p; done
+
+NB: you can use directly the source from the community:
+    URL: git://git.denx.de/u-boot.git
+    Branch: ##GIT_BRANCH##
+    Revision: ##GIT_SRCREV##
+
+    $> git clone git://git.denx.de/u-boot.git
+    $> cd <directory of U-Boot source code>
+    $> git checkout -b WORKING ##GIT_SRCREV##
+    $> for p in `ls -1 <path to patch>/*.patch`; do git am $p; done
+
+5. Compilation U-Boot source code:
+--------------------------------
+To compile U-Boot source code, first move to U-Boot source:
+    $> cd <directory to U-Boot source code>
+
+You can call the specific 'Makefile.sdk' provided to compile U-Boot:
+  - Display 'Makefile.sdk' file default configuration and targets:
+    $> make -f $PWD/../Makefile.sdk help
+  - Compile default U-Boot configuration:
+    $> make -f $PWD/../Makefile.sdk all
+
+Default U-Boot configuration is done in 'Makefile.sdk' file through two specific
+variables 'DEVICE_TREE' and 'UBOOT_CONFIGS':
+  - 'DEVICE_TREE' is a list of device tree to build, using 'space' as separator.
+    ex: DEVICE_TREE="<devicetree1> <devicetree2>"
+  - 'UBOOT_CONFIGS' is a list of '<defconfig>,<type>,<binary>' configurations,
+        <defconfig> is the u-boot defconfig to use to build
+        <type> is the name append to u-boot binaries (ex: 'trusted', 'basic', etc)
+        <binary> is the u-boot binary to export (ex: 'u-boot.bin', 'u-boot.stm32', etc)
+    ex: UBOOT_CONFIGS="<defconfig1>,basic,u-boot.bin <defconfig1>,trusted,u-boot.stm32"
+You can override the default U-Boot configuration if you specify these variables:
+  - Compile default U-Boot configuration but applying specific devicetree(s):
+    $> make -f $PWD/../Makefile.sdk all DEVICE_TREE="<devicetree1> <devicetree2>"
+  - Compile for a specific U-Boot configuration:
+    $> make -f $PWD/../Makefile.sdk all UBOOT_CONFIGS=<u-boot defconfig>,<u-boot type>,<u-boot binary>
+  - Compile for a specific U-Boot configuration and applying specific devicetree(s):
+    $> make -f $PWD/../Makefile.sdk all UBOOT_CONFIGS=<u-boot defconfig>,<u-boot type>,<u-boot binary> DEVICE_TREE="<devicetree1> <devicetree2>"
+
+6. Update software on board:
+----------------------------
+6.1. partitioning of binaries:
+-----------------------------
+There are two possible configurations available:
+- Basic configuration
+- Trusted configuration
+
+U-Boot build provides binaries for each configuration:
+- Basic configuration: U-Boot SPL and U-Boot imgage (for FSBL and SSBL)
+- Trusted configuration: U-Boot binary with ".stm32" extension (for SSBL)
+
+Basic configuration:
+On this configuration, we use U-Boot SPL as First Stage Boot Loader (FSBL) and
+U-Boot as Second Stage Boot Loader (SSBL).
+U-Boot SPL (u-boot-spl*.stm32) MUST be copied on a dedicated partition named "fsbl1"
+U-Boot image (u-boot*.img) MUST be copied on a dedicated partition named "ssbl"
+
+Trusted configuration:
+On this configuration, U-Boot is associated to Trusted Firmware (TF-A) and only
+U-Boot image is used as Second Stage Boot Loader (SSBL).
+TF-A binary (tf-a-*.stm32) MUST be copied on a dedicated partition named "fsbl1"
+U-boot binary (u-boot*.stm32) MUST be copied on a dedicated partition named "ssbl"
+
+6.2. Update via SDCARD:
+-----------------------
+Basic configuration
+* u-boot-spl*.stm32
+  Copy the binary on the dedicated partition, on SDCARD/USB disk the partition
+  "fsbl1" is the partition 1:
+  - SDCARD: /dev/mmcblkXp1 (where X is the instance number)
+  - SDCARD via USB reader: /dev/sdX1 (where X is the instance number)
+  dd if=<U-Boot SPL file> of=/dev/<device partition> bs=1M conv=fdatasync
+
+* u-boot*.img
+  Copy the binary on the dedicated partition, on SDCARD/USB disk the partition
+  "ssbl" is the partition 4:
+  - SDCARD: /dev/mmcblkXp3 (where X is the instance number)
+  - SDCARD via USB reader: /dev/sdX3 (where X is the instance number)
+  dd if=<U-Boot image file> of=/dev/<device partition> bs=1M conv=fdatasync
+
+Trusted configuration
+* tf-a-*.stm32
+  Copy the binary on the dedicated partition, on SDCARD/USB disk the partition
+  "fsbl1" is the partition 1:
+  - SDCARD: /dev/mmcblkXp1 (where X is the instance number)
+  - SDCARD via USB reader: /dev/sdX1 (where X is the instance number)
+  dd if=<TF-A binary file> of=/dev/<device partition> bs=1M conv=fdatasync
+
+* u-boot*.stm32
+  Copy the binary on the dedicated partition, on SDCARD/USB disk the partition
+  "ssbl" is the partition 4:
+  - SDCARD: /dev/mmcblkXp3 (where X is the instance number)
+  - SDCARD via USB reader: /dev/sdX3 (where X is the instance number)
+  dd if=<U-Boot stm32 binary file> of=/dev/<device partition> bs=1M conv=fdatasync
+
+FAQ: to found the partition associated to a specific label, just plug the
+SDCARD/USB disk on your PC and call the following command:
+  $> ls -l /dev/disk/by-partlabel/
+total 0
+lrwxrwxrwx 1 root root 10 Jan 17 17:38 bootfs -> ../../mmcblk0p4
+lrwxrwxrwx 1 root root 10 Jan 17 17:38 fsbl1 -> ../../mmcblk0p1     ➔ FSBL (TF-A)
+lrwxrwxrwx 1 root root 10 Jan 17 17:38 fsbl2 -> ../../mmcblk0p2     ➔ FSBL backup (TF-A backup – same content as FSBL)
+lrwxrwxrwx 1 root root 10 Jan 17 17:38 rootfs -> ../../mmcblk0p5
+lrwxrwxrwx 1 root root 10 Jan 17 17:38 ssbl -> ../../mmcblk0p3      ➔ SSBL (U-Boot)
+lrwxrwxrwx 1 root root 10 Jan 17 17:38 userfs -> ../../mmcblk0p6
+
+6.3. Update via USB mass storage on U-Boot:
+-------------------------------------------
+* Plug the SDCARD on Board.
+* Start the board and stop on U-Boot shell:
+ Hit any key to stop autoboot: 0
+ STM32MP>
+* plug an USB cable between the PC and the board via USB OTG port.
+* On U-Boot shell, call the usb mass storage functionality:
+ STM32MP> ums 0 mmc 0
+ ums <USB controller> <dev type: mmc|usb> <dev[:part]>
+  ex.:
+    ums 0 mmc 0
+    ums 0 usb 0
+
+* Follow section 6.2 to put U-Boot SPL binary and U-Boot binary (*.img or *.stm32)
+  on SDCARD/USB disk.
