Command to rebuild firmware after a config change.
After you make a change to the firmware version in the master configuration,
run this script to test it. It will rebuild the master configuration, update
the Manifest and build the new firmware. You can then submit your CL to update
the master configuration, safe in the knowledge that you have tested it.
Usage:
cros_update_firmware <board>
where <board> is the board whose firmware needs updating (e.g. 'coral').
