commit 1ec8925c7f1ea7c64c95b44c9d915544869e6c1c
Author: Stefan Reinauer <stefan.reinauer at coreboot.org>
Date:   Mon Apr 27 14:04:38 2015 -0700

    kbuild: automatically include northbridges
    
    This change switches all northbridge vendors and southbridges
    to be autoincluded by Makefile.inc, rather than having to be
    mentioned explicitly in northbridge/Makefile.inc or in
    northbridge/<vendor>/Makefile.inc.
    
    This means, vendor and northbridge directories are now "drop
    in", e.g. be placed in the coreboot directory hierarchy
    without having to modify any higher level coreboot files.
    
    The long term plan is to enable out of tree components to be
    built with a given coreboot version (given that the API did not
    change).
