  Usage:
    $(basename $0) --help

    Bootloader build script.

    command list:
    1. build default uboot:
        ./$(basename $0) [config_name]

    2. build uboot with specified bl[x].bin
        ./$(basename $0) [config_name] --bl[x] [path]

    3. build uboot with bl[x]/src source code
        ./$(basename $0) [config_name] --update-bl[x]

    4. print config list
        ./$(basename $0) --config

    5. check compile status with filter(optional)
        ./$(basename $0) --check-compile [filter]

    6. update aml ddr fw by source code (for g12a and later use)
        ./$(basename $0) [config_name] --update-bl2 --ddrfw

    7. build uboot with bl[x]/src source code, and run coverity defect
        ./$(basename $0) [config_name] --update-bl[x] --cov
        ./$(basename $0) [config_name] --update-bl[x] --cov-high [path]

    8. build uboot with ramdump function
        ./$(basename $0) [config_name] --update-bl[x] --enable-ramdump --chipid [cpu_id]

    Example:
    1) ./$(basename $0) gxb_p200_v1
      build gxb_p200_v1 config

    2) ./$(basename $0) gxb_p200_v1 --bl2 fip/bl2.bin --bl30 fip/bl30.bin
      build gxb_p200_v1 with specified bl2.bin and bl30.bin

    3) ./$(basename $0) gxb_p200_v1 --update-bl31 --update-bl2
      build gxb_p200_v1 with bl31/bl2 source code

    4) ./$(basename $0) --config
      print config list

    5) ./$(basename $0) --check-compile skt
      check all skt board compile status

    6) ./$(basename $0) sc2_ah212 --update-bl2 --update-bl2e --enable-ramdump --chipid 00D9C73147101D16
       build uboot with ramdump function, chipid for bl2.

    Remark:
    bl[x].bin/img priority:
    1. uboot will use binaries under bl[x]/bin/ folder by default, bl[x] version specified in .repo/manifest.xml
    2. if you want use your own bl[x].bin, specify path by add "--bl[x] [path]" parameter
    3. if you want use bl[x].bin by compile source code, please add "--update-bl[x]" parameter
