From a6ac1877316216c8c56a9ab04b9ac3cde6ab01aa Mon Sep 17 00:00:00 2001 From: Kyösti Mälkki Date: Sat, 25 Jun 2016 11:40:00 +0300 Subject: intel/gm45: Use romstage_handoff for S3 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Don't use scratchpad registers when we have romstage_handoff to pass S3 resume flag. Also fixes console log from reporting early in ramstage "Normal boot" while on S3 resume path.
