commit e8d1f1146f089e95603819ba3cd7b3885e6d9fce Author: David Hendricks dhendrix@chromium.org Date: Mon Sep 29 13:37:51 2014 -0700
pinky: Move some init to mainboard bootblock
This patch moves init for I2C, SPI, ChromeOS GPIOs to the board-specific bootblock init function on Pinky, the idea being to isolate SoC code so that it's more readily adaptable for different boards.
BUG=none BRANCH=none TEST=built and booted on Pinky
