commit ccbb5d570902e3ee45691bb234962cddd508c2a7
Author: Martin Roth <martinroth at google.com>
Date:   Fri Dec 11 12:24:33 2015 -0700

    Payloads: Add U-Boot as a coreboot-payload
    
    - Add Kconfig and Makefile options to use U-Boot as a payload.
    - Add Kconfig option for extra cbfstool command line arguments.
    - Add Kconfig & Makefile option to load the payload as a flat binary.
    - Add u-boot directory to .gitignore.
    
    This is currently working for X-86 only.
    I haven't tried graphics.
    
    Tested in QEMU and on Minnowboard Max
