commit 5856a95a018302e592d08f5f5349c16a8e2b6dc2 Author: Aaron Durbin adurbin@chromium.org Date: Mon Jan 25 17:56:43 2016 -0600
google/lars: 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).
