From 37e1f42d28dd747a8485d3a0dcd00375124ef727 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Thu, 14 Nov 2013 13:47:08 -0600 Subject: [PATCH] baytrail: ensure init_chromeos() is called in romstage The TPM needs to have the TPM_Startup command sent to it on all boot paths. The call init_chromeos() in romstage_common() fulfills this requirement. BUG=chrome-os-partner:24057 BRANCH=None TEST=Built and booted. Was able to suspend to ram multiple times in a row.
