From 40d0bfa212d5516c68d3ad044334f7d2cc6b4445 Mon Sep 17 00:00:00 2001 From: Daisuke Nojiri Date: Thu, 30 Nov 2017 17:41:09 -0800 Subject: cr50: Make EC clear AP_OFF before hibnernate This patch makes AP send EC_REBOOT_HIBERNATE_CLEAR_AP_OFF, which makes EC clear AP_OFF flag then hibernate. This is needed to make Chromebox boot when cr50 toggles the EC's reset line after TURN_UPDATE_ON command. BUG=b:69721737 BRANCH=none CQ-DEPEND=CL:802632 TEST=Verify Fizz reboot after cr50 update.
