commit 690531fee1a01023c7dfefb6ec8bb5687762ec1b Author: Aaron Durbin adurbin@chromium.org Date: Wed Oct 2 11:06:31 2013 -0500
baytrail: import and use updated mrc_wrapper.h
The mrc_wrapper.h was changed to protect against ABI differences between the two sets of compilers and flags used. This requires a prope shim for the console output funciton.
BUG=chrome-os-partner:23048 BRANCH=None TEST=Built and booted successfully.
