Usage: build-image-common [OPTIONS]
Build raspberrypi image.

Options:
  -n, --name IMAGE_NAME            The raspberrypi image name to be built.
  -k, --kernel KERNEL_URL          The URL of kernel source's repository, which defaults to https://gitee.com/openeuler/raspberrypi-kernel.git.
  -b, --branch KERNEL_BRANCH       The branch name of kernel source's repository, which defaults to openEuler-20.03-LTS.
  -c, --config KERNEL_DEFCONFIG    The name/path of defconfig file when compiling kernel, which defaults to openeuler-raspi_defconfig.
  -r, --repo REPO_INFO             Required! The URL/path of target repo file or list of repo's baseurls which should be a space separated list.
  -s, --spec SPEC                  The image's specification: headless, xfce, ukui, dde, gnome, devstation or the file path of rpmlist. The default is headless.
  --cores N                        The number of cpu cores to be used during making.
  -h, --help                       Show command help.
