From 04c5bae39054aedbff1865d9dd2633260c23ece3 Mon Sep 17 00:00:00 2001 From: Duncan Laurie Date: Mon, 13 Aug 2012 09:37:42 -0700 Subject: Define post codes for OS boot and resume And move the pre-hardwaremain post code to 0x79 so it comes before hardwaremain at 0x80. Emit these codes from ACPI OS resume vector as well as the finalize step in bd82x6x southbridge.
