[coreboot] [commit] r6182 - in trunk: . src/arch/x86

[repository service]

Author: oxygene
Date: Thu Dec 16 08:36:28 2010
New Revision: 6182
URL: https://tracker.coreboot.org/trac/coreboot/changeset/6182

Log:
Add support for cbfs-files-y to the build system.
That variable allows chipset components to add files to
the CBFS image, for details see
http://www.coreboot.org/pipermail/coreboot/2010-December/062483.html

Compared to the patch in that mail this commit improves dependency
tracking a bit.
