   1 U-Boot for Amlogic U200
   2 =======================
   3
   4 U200 is a reference board manufactured by Amlogic with the following
   5 specifications:
   6
   7  - Amlogic S905D2 ARM Cortex-A53 quad-core SoC
   8  - 2GB DDR4 SDRAM
   9  - 10/100 Ethernet (Internal PHY)
  10  - 1 x USB 3.0 Host
  11  - eMMC
  12  - SDcard
  13  - Infrared receiver
  14  - SDIO WiFi Module
  15  - MIPI DSI Connector
  16  - Audio HAT Connector
  17  - PCI-E M.2 Connector
  18
  19 Schematics are available from Amlogic on demand.
  20
  21 Currently the u-boot port supports the following devices:
  22  - serial
  23  - Ethernet
  24  - Regulators
  25  - Clock controller
  26
  27 u-boot compilation
  28 ==================
  29
  30  > export CROSS_COMPILE=aarch64-none-elf-
  31  > make u200_defconfig
  32  > make
  33
  34 Image creation
  35 ==============
  36
  37 Amlogic doesn't provide sources for the firmware and for tools needed
  38 to create the bootloader image, so it is necessary to obtain them from
  39 the git tree published by the board vendor:
  40
  41  > wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
  42  > wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz

  44  > tar xvfJ gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz
  45  > export PATH=$PWD/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux/bin:$PWD/gcc-linaro-arm-none-eabi-4.8-2013.11_linux/bin:$PATH
  46  > git clone https://github.com/BayLibre/u-boot.git -b buildroot-openlinux-20180418 amlogic-u-boot
  47  > cd amlogic-u-boot
  48  > make g12a_u200_v1_defconfig
  49  > make
  50  > export UBOOTDIR=$PWD
  51
  52 Download the latest Amlogic Buildroot package, and extract it :
  53  > wget http://openlinux2.amlogic.com:8000/ARM/filesystem/Linux_BSP/buildroot_openlinux_kernel_4.9_fbdev_20180706.tar.gz
  54  > tar xfz buildroot_openlinux_kernel_4.9_fbdev_20180706.tar.gz buildroot_openlinux_kernel_4.9_fbdev_20180706/bootloader
  55  > export BRDIR=$PWD/buildroot_openlinux_kernel_4.9_fbdev_20180706
  56  > export FIPDIR=$BRDIR/bootloader/uboot-repo/fip
  57
  58 Go back to mainline U-Boot source tree then :
  59  > mkdir fip
