This fastboot prebuild binary is build based on kernelflinger + Efiwrapper.
It can be run standalone without UEFI runtime service support. It aims to
provide convenient fastboot flash function for non android product provision.
Thus it's NOT target to become "fastboot" which support all feature required
by Google branded Android device.

Command Support:
    1)fastboot flash <partition> <filename> //flash gpt or flash some
      data to a disk partition or some special data.
    2)fastboot erase <partition> //erase a partition.
    3)fastboot gatvar <var_name>|all //get a var value or all vars value
    4)fastboot reboot //Reboot the device.
