commit f7f639012289bcb398ab097b72ec259db69d13ef
Author: Elyes <ehaouas at noos.fr>
Date: Thu May 29 12:04:25 2014 +0200
New board: 945g-m4 (LGA775 i945GC i82801gx w83627ehg)
add-in PCIe card removed from devicetree.cb
mptable.c and irq_tables generated using coreboot tree utils (without PCIe and without the
DVB card).
board_info.txt fixed
To Fix: The system hangs on "Setting up Root Complex Topology"
Change-Id: I7b00251e332ac005918cf7c3ed4bef8878bd145b
