From 0dca6490b9b0ff2fd91dc3d396574447b1a39c1e Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Wed, 13 Jul 2016 11:54:12 -0500 Subject: [PATCH] soc/intel/braswell: don't duplicate setting ACPI sleep state MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The ramstage main() in lib/hardwaremain.c has the logic to set the ACPI sleep state based on romstage_handoff. Thus, there's no need to do it a second time.
