commit facd5fc99b0fea5594ce29417b58d138248b4429 Author: Todd Broch tbroch@chromium.org Date: Fri Jun 6 17:03:49 2014 -0700
nyan: Ignore the recovery GPIO.
CrOS devices with Chromeos EC need only use hostevent to communicate recovery assertion to the BIOS. This CL removes wired GPIO from determining recovery as it appears under certain conditions (cold reset) the internal PU on the AP isn't strong enough and therefore the value is sometimes seen as asserted.
BRANCH=none BUG=chrome-os-partner:29333 TEST=compiles & BIOS no longer responds to rec_mode GPIO during boot.
