From 00bf3dbf350b48e78aab413958ec83692d8fa263 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Thu, 9 Jan 2014 10:33:23 -0600 Subject: baytrail: snapshot power state in romstage MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The memory reference code doesn't maintain some of the registers which contain valuable information in order to log correct reset and wake events in the eventlog. Therefore snapshot the registers which matter in this area so that they can be consumed by ramstage. BUG=chrome-os-partner:24907 BRANCH=rambi,squawks TEST=Did various resets/wakes with logging patch which consumes this structure. Eventlog can pick up reset events and power failures.
