From 8e7928a6fe05a295ca412cb6a6df509de7b73f13 Mon Sep 17 00:00:00 2001 From: Iru Cai Date: Sun, 18 Oct 2015 23:40:34 +0800 Subject: sandybridge/gma_lvds: support both Sandy&Ivy on one board Sandy and Ivy Bridge processors use the same socket, and a mainboard with the socket can support both types of CPUs. However, they use different native graphics init code for LVDS and cause a crash if running the wrong code. This change detects the CPU type and then selects the right code to run. It will add some more code in ramstage. It also merges the {SANDY,IVY}BRIDGE_LVDS symbol to one SANDYBRIDGE_IVYBRIDGE_LVDS.
