   2 =======================
   3
   4 LibreTech CC is a single board computer manufactured by Libre Technology
   5 with the following specifications:
   6
   7  - Amlogic S905X ARM Cortex-A53 quad-core SoC @ 2GHz
   8  - ARM Mali 450 GPU
   9  - 2GB DDR3 SDRAM
  10  - Gigabit Ethernet
  11  - HDMI 2.0 4K/60Hz display
  12  - 40-pin GPIO header
  13  - 4 x USB 2.0 Host, 1 x USB OTG

  23
  24 U-Boot compilation
  25 ==================
  26
  27  > export ARCH=arm
  28  > export CROSS_COMPILE=aarch64-none-elf-
  29  > make libretech-cc_defconfig
  30  > make
  31
  32 Image creation
  33 ==============
  34
  35 Amlogic doesn't provide sources for the firmware and for tools needed
  36 to create the bootloader image, so it is necessary to obtain them from
  37 the git tree published by the board vendor:
  38
  39  > wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz

  42  > tar xvfJ gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz
  43  > 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:$PATH
  44  > git clone https://github.com/BayLibre/u-boot.git -b libretech-cc amlogic-u-boot
  45  > cd amlogic-u-boot
  46  > make libretech_cc_defconfig
  47  > make
  48  > export FIPDIR=$PWD/fip
  49
  50 Go back to mainline U-Boot source tree then :
  51  > mkdir fip
  52
  53  > cp $FIPDIR/gxl/bl2.bin fip/
  54  > cp $FIPDIR/gxl/acs.bin fip/
  55  > cp $FIPDIR/gxl/bl21.bin fip/

  77         fip/bl21_zero.bin \
  78         fip/bl2_new.bin \
  79         bl2
  80
  81  > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl30_new.bin
  82  > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl31.img
  83  > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl33.bin

  90                 --bl33 fip/bl33.bin.enc
  91
  92 and then write the image to SD with:
  93
  94  > DEV=/dev/your_sd_device
  95  > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1
  96  > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=1 count=444
