commit c38301601de3c043dd7802b32ad295a6f954b55e Author: Gabe Black gabeblack@google.com Date: Wed Jun 19 03:29:45 2013 -0700
pit: Replace the snow GPIO indexes with ones for pit.
The GPIOs used by vboot and setting up the display and backlight were still the ones for snow. This change updates them so they're correct for pit.
