commit 9ed4b8f3aef177e556c0e16cd1da27ba3bca2f4d
Author: Cristian Măgherușan-Stanciu <cristi.magherusan at gmail.com>
Date:   Sun Jun 19 03:03:28 2011 +0200

    Add the coreboot config to CBFS
    The CBFS will contain a new file, named 'config' of type 'raw' that is a
    stripped-down version of the .config file that was used to build
    coreboot. For space savings, all the comments and empty lines were
    removed from the original config.
    This is done in order to easily reproduce the process of creating an
    image made by someone else when only having the original binary image.
