From b86113fd9ade587f7cb69b8c0c5d6407917fb185 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Tue, 19 Feb 2013 08:59:16 -0600 Subject: haswell: RESET_ON_INVALID_RAMSTAGE_CACHE option The RESET_ON_INVALID_RAMSTAGE_CACHE option indicates what to do when the ramstage cache is found to be invalid on a S3 wake. If selected the system will perform a system reset on S3 wake when the ramstage cache is invalid. Otherwise it will signal to load the ramstage from cbfs.
