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

  48  > 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:$PATH
  49  > git clone https://github.com/khadas/u-boot -b Vim vim-u-boot
  50  > cd vim-u-boot
  51  > make kvim_defconfig
  52  > make CROSS_COMPILE=aarch64-none-elf-
  53  > export FIPDIR=$PWD/fip
  54
  55 Go back to mainline U-Boot source tree then :
  56  > mkdir fip
  57
  58  > cp $FIPDIR/gxl/bl2.bin fip/
  59  > cp $FIPDIR/gxl/acs.bin fip/
  60  > cp $FIPDIR/gxl/bl21.bin fip/
  61  > cp $FIPDIR/gxl/bl30.bin fip/
  62  > cp $FIPDIR/gxl/bl301.bin fip/

  70         fip/bl301.bin \
  71         fip/bl301_zero.bin \
  72         fip/bl30_new.bin \
  73         bl30
  74
  75  > python $FIPDIR/acs_tool.pyc fip/bl2.bin fip/bl2_acs.bin fip/acs.bin 0
  76
  77  > $FIPDIR/blx_fix.sh \
  78         fip/bl2_acs.bin \
  79         fip/zero_tmp \
  80         fip/bl2_zero.bin \
  81         fip/bl21.bin \
  82         fip/bl21_zero.bin \
  83         fip/bl2_new.bin \
  84         bl2
  85
  86  > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl30_new.bin
  87  > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl31.img
  88  > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl33.bin
  89  > $FIPDIR/gxl/aml_encrypt_gxl --bl2sig --input fip/bl2_new.bin --output fip/bl2.n.bin.sig

  95                 --bl33 fip/bl33.bin.enc
  96
  97 and then write the image to SD with:
  98
  99  > DEV=/dev/your_sd_device
 100  > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1
 101  > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=1 count=444
