# Usage function

${SH_FILE} is used to compile, generate and burn official U-Boot for Amlogic GXL/GXM SoC

Usage: ${SH_FILE} [a-] -b board [-d] [-g] [-h] [-n]

Where:
  -a    use official ARM ATF fimrware
  -b    name of the board to configure
  -d    compile firmware in debug mode (when allowed)
  -g    use gxlimg to generate image instead of aml_encrypt_gxl
  -h    this help page
  -n    don't compile Amlogic U-Boot (use pre-compiled binary blob)

Currently supported Amlogic boards are: khadas-vim, khadas-vim2, libretech-cc and libretech-ac
