   2 =======================
   3
   4 P201 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  - 10/100 Ethernet
  11  - HDMI 2.0 4K/60Hz display
  12  - 2 x USB 2.0 Host
  13  - eMMC, microSD
  14  - Infrared receiver

  31 u-boot compilation
  32 ==================
  33
  34  > export CROSS_COMPILE=aarch64-none-elf-
  35  > make p201_defconfig
  36  > make
  37
  38 Image creation
  39 ==============
  40
  41 Amlogic doesn't provide sources for the firmware and for tools needed
  42 to create the bootloader image, so it is necessary to obtain them from
  43 the git tree published by the board vendor:
  44
  45  > wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
  46  > wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz

  49  > 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:$PATH
  50  > git clone https://github.com/BayLibre/u-boot.git -b n-amlogic-openlinux-20170606 amlogic-u-boot
  51  > cd amlogic-u-boot
  52  > make gxb_p201_v1_defconfig
  53  > make
  54  > export FIPDIR=$PWD/fip
  55
  56 Go back to mainline U-boot source tree then :
  57  > mkdir fip
  58
  59  > cp $FIPDIR/gxl/bl2.bin fip/
  60  > cp $FIPDIR/gxl/acs.bin fip/

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

  97
  98 and then write the image to SD with:
  99
 100  > DEV=/dev/your_sd_device
 101  > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1
 102  > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=1 count=444
