commit c21f7dde830b448a2fb86d574d695d10b5c0b07f
Author: Bora Guvendik <bora.guvendik at intel.com>
Date: Fri Dec 9 11:14:43 2016 -0800
Pass the firmware sdhci data to deptcharge
Write sdhci and mmc driver data to coreboot
tables so that payload can use the data
and start talking to emmc without
reinitializing the storage driver.
BUG=chrome-os-partner:59875
BRANCH=reef
TEST=None
