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

and then write the image to SD with:

 > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1
 > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=1 count=444
