From 48b2adae1c3ba0c23630f912fd7f7c87f0a7528c Mon Sep 17 00:00:00 2001 From: Eric Lai Date: Tue, 28 May 2019 13:49:44 +0800 Subject: mb/google/sarien: Modify SSD power sequence Due to we turn off SSD power in S5. CB:32952 Based on M2 spec we have to turn on SSD power before RST assert. BUG=b:133389422 TEST=verify warm boot and cold boot are boot successfully.
