+U-Boot for Amlogic S400
+=======================
+
+S400 is a reference board manufactured by Amlogic with the following
+specifications:
+
+ - Amlogic A113DX ARM Cortex-A53 quad-core SoC @ 1.2GHz
+ - 1GB DDR4 SDRAM
+ - 10/100 Ethernet
+ - 2 x USB 2.0 Host
+ - eMMC
+ - Infrared receiver
+ - SDIO WiFi Module
+ - MIPI DSI Connector
+ - Audio HAT Connector
+ - PCI-E M.2 Connectors
+
+Schematics are available from Amlogic on demand.
+
+Currently the u-boot port supports the following devices:
+ - serial
+ - eMMC
+ - Ethernet
+ - I2C
+ - Regulators
+ - Reset controller
+ - Clock controller
+ - USB Host
+ - ADC
+
+u-boot compilation
+==================
+
+ > export ARCH=arm
+ > export CROSS_COMPILE=aarch64-none-elf-
+ > make s400_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:

+ > git clone https://github.com/BayLibre/u-boot.git -b n-amlogic-openlinux-20170606 amlogic-u-boot
+ > cd amlogic-u-boot
+ > make axg_s400_v1_defconfig
+ > make
+ > export FIPDIR=$PWD/fip
+
+Go back to mainline U-boot source tree then :
+ > mkdir fip
