From 6097e193fc708942931fd60ad40d40e95550ecb0 Mon Sep 17 00:00:00 2001 From: Stefan Reinauer Date: Mon, 11 Jun 2012 15:38:15 -0700 Subject: Make ACPI code detect Sandy/Ivy Bridge dynamically On systems with socketed CPUs we want to be able to drop in a Sandy Bridge or Ivy Bridge CPU without recompiling the firmware. Hence, detect the north bridge dynamically. In order for this to work, we need Ivy Bridge MRC and coreboot configured for Ivy Bridge.
