+U-Boot for Amlogic U200
+=======================
+
+U200 is a reference board manufactured by Amlogic with the following
+specifications:
+
+ - Amlogic S905D2 ARM Cortex-A53 quad-core SoC
+ - 2GB DDR4 SDRAM
+ - 10/100 Ethernet (Internal PHY)
+ - 1 x USB 3.0 Host
+ - eMMC
+ - SDcard
+ - Infrared receiver
+ - SDIO WiFi Module
+ - MIPI DSI Connector
+ - Audio HAT Connector
+ - PCI-E M.2 Connector
+
+Schematics are available from Amlogic on demand.
+
+Currently the u-boot port supports the following devices:
+ - serial
+ - Ethernet
+ - Regulators
+ - Clock controller
+
+u-boot compilation
+==================
+
+ > export ARCH=arm
+ > export CROSS_COMPILE=aarch64-none-elf-
+ > make u200_defconfig
+ > make
+
+Image creation
+==============
+
+Amlogic doesn't provide sources for the firmware and for tools needed
+to create the bootloader image, so it is necessary to obtain them from
+the git tree published by the board vendor:
+
+ > wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz

+ > git clone https://github.com/BayLibre/u-boot.git -b buildroot-openlinux-20180418 amlogic-u-boot
+ > cd amlogic-u-boot
+ > make g12a_u200_v1_defconfig
+ > make
+ > export UBOOTDIR=$PWD
+
+Download the latest Amlogic Buildroot package, and extract it :
+ > wget http://openlinux2.amlogic.com:8000/ARM/filesystem/Linux_BSP/buildroot_openlinux_kernel_4.9_fbdev_20180706.tar.gz
+ > tar xfz buildroot_openlinux_kernel_4.9_fbdev_20180706.tar.gz buildroot_openlinux_kernel_4.9_fbdev_20180706/bootloader
+ > export BRDIR=$PWD/buildroot_openlinux_kernel_4.9_fbdev_20180706
+ > export FIPDIR=$BRDIR/bootloader/uboot-repo/fip
+
+Go back to mainline U-Boot source tree then :
+ > mkdir fip
+
+ > wget https://github.com/BayLibre/u-boot/releases/download/v2017.11-libretech-cc/blx_fix_g12a.sh -O fip/blx_fix.sh
