The following set of patches are an updated version of the patch I posted on 27 Dec 2007. I tried to incorporate most of the feedback from Uwe and others.
I added GPLv2 license headers throughout, and preserved existing copyrights except where Uwe indicated otherwise. I did not add copyrights for other people, as I do not know the exact name and date. For files that are forked from other code in coreboot, I added a comment saying so; if the copyright holders decide to assert ownership for the original files, we can add them to the derived files as well.
