commit 9ab31dff0a170c78a538787044e8d9b10be36311 Author: Aaron Durbin adurbin@chromium.org Date: Mon Jan 25 17:43:45 2016 -0600
google/glados: perform early init for CAR *stage
In order to support both separate verstage and a verified boot after romstage one needs to ensure the proper GPIO and EC configuration been complete. Therefore, move that logic to car_mainboard_post_console_init() in car.c file which gets called in the early flow of a CAR stage (either verstage or romstage).
BUG=chrome-os-partner:44827 BRANCH=glados TEST=Built glados w/ separate verstage and booted.
