(cherry-pick back to ToT) FAFT needs these buttons (VolUp and VolDown) be controllable such that it can automate the firmware mode switching flows. It is done by EC overwriting the GPIO values such that AP can see the results. BRANCH=ToT,smaug BUG=None TEST=AP boots into the firmware menu screen. Run the following commands in EC console: > btnpress voldown 1 > btnpress voldown 0 # See the next option selected, like a real button pressed > btnpress volup 1 > btnpress volup 0 # Boot in the selected option, like a real button pressed > btnpress volup Button volup pressed = 0 Change-Id: I5e0b514d9986b8e5729ffd3560560d650669e0b7 Signed-off-by: Vic Yang <victoryang@google.com> Signed-off-by: Tom Wai-Hong Tam <waihong@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/294882 Reviewed-by: Randall Spangler <rspangler@chromium.org> (cherry picked from commit 77291b156d10f31dd059a4662aa249a8f8ea762e) Reviewed-on: https://chromium-review.googlesource.com/295162
