   2 =======================
   3
   4 P200 is a reference board manufactured by Amlogic with the following
   5 specifications:
   6
   7  - Amlogic S905 ARM Cortex-A53 quad-core SoC @ 1.5GHz
   8  - ARM Mali 450 GPU
   9  - 2GB DDR3 SDRAM
  10  - Gigabit Ethernet
  11  - HDMI 2.0 4K/60Hz display
  12  - 2 x USB 2.0 Host
  13  - eMMC, microSD
  14  - Infrared receiver

  17
  18 Schematics are available from Amlogic on demand.
  19
  20 Currently the u-boot port supports the following devices:
  21  - serial
  22  - eMMC, microSD
  23  - Ethernet

  30
  31 u-boot compilation
  32 ==================
  33
  34  > export ARCH=arm
  35  > export CROSS_COMPILE=aarch64-none-elf-
  36  > make p200_defconfig
  37  > make
  38
  39 Image creation
  40 ==============
  41
  42 Amlogic doesn't provide sources for the firmware and for tools needed
  43 to create the bootloader image, so it is necessary to obtain them from
  44 the git tree published by the board vendor:
  45
  46  > wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
  47  > wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz

  50  > 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:$PATH
  51  > git clone https://github.com/BayLibre/u-boot.git -b n-amlogic-openlinux-20170606 amlogic-u-boot
  52  > cd amlogic-u-boot
  53  > make gxb_p200_v1_defconfig
  54  > make
  55  > export FIPDIR=$PWD/fip
  56
  57 Go back to mainline U-boot source tree then :
  58  > mkdir fip
  59
  60  > cp $FIPDIR/gxl/bl2.bin fip/
  61  > cp $FIPDIR/gxl/acs.bin fip/

  84         fip/bl21_zero.bin \
  85         fip/bl2_new.bin \
  86         bl2
  87
  88  > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl30_new.bin
  89  > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl31.img
  90  > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl33.bin

  99 and then write the image to SD with:
 100
 101  > DEV=/dev/your_sd_device
 102  > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1
