It's a little more complicated. Looking at
http://review.coreboot.org/#/c/3568/ I think you'll need to do the
following:

git revert 1cc3416f5fb58883fdad7192856c258c01909fd7

Then set the mrc blob path to systemagent-sandybridge.bin.

You might be hitting the same issues Kyosti was hitting.

Lemme know how it goes.
