  20 U-Boot compilation
  21 ------------------
  22
  23 .. code-block:: bash
  24
  25     $ export CROSS_COMPILE=aarch64-none-elf-
  26     $ make odroid-n2_defconfig
  27     $ make

  29 Image creation
  30 --------------
  31
  32 Amlogic doesn't provide sources for the firmware and for tools needed
  33 to create the bootloader image, so it is necessary to obtain them from
  34 the git tree published by the board vendor:
  35
  36 .. code-block:: bash
  37
  38     $ wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
