__usage="
Usage: build_u-boot [OPTIONS]
Build Rockchip u-boot image.
The target files idbloader.img and u-boot.itb will be generated in the build/u-boot folder of the directory where the build_u-boot.sh script is located.

Options: 
  -u, --ubootconfig         UBOOT_DEFCONFIG    Required! The name of defconfig file when compiling u-boot, which defaults to firefly-rk3399_defconfig, set none to use prebuild u-boot image.
  --cores N                 The number of cpu cores to be used during making.
  -h, --help                Show command help.
