From 1b7609c0e88ba820dbc2251fad0d994e2b54a154 Mon Sep 17 00:00:00 2001 From: Kyösti Mälkki Date: Sat, 25 Jun 2016 11:40:00 +0300 Subject: intel/nehalem: 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.
