From 1be16f08f293f619d7259acd245ad5290a75ba96 Mon Sep 17 00:00:00 2001 From: Hung-Te Lin Date: Mon, 23 Jul 2018 21:26:18 +0800 Subject: google/kukui: Enable eMMC in bootblock. On kukui board, the eMMC is routed to EC for boot ROM emulation when loading bootblock, and should be set back to real eMMC as early as possible after bootblock is loaded. BUG=b:80501386 TEST=make; boots and verified BOOTBLOCK_EN_L GPIO is enabled.
