This patch resolves the outstanding issues with PCI device enumeration and getting the board to boot into GNU/Linux with VGA rom. Previously the board would not boot to GNU/Linux with video, even if VGA rom was used. Bugs in the devicetree were fixed according to superiotool output. Tested on GA-B75M-D3H with VGA rom. Booted to GNU/Linux (Fedora 22 4.0.4-301.fc22.x86_64) Change-Id: Ide1f406652659e6f99ee5d993719c187650fffe4 Signed-off-by: Damien Zammit <damien@zamaudio.com> Reviewed-on: http://review.coreboot.org/10895 Tested-by: build bot (Jenkins) Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Felix Held <felix-coreboot@felixheld.de> Reviewed-by: Alexandru Gagniuc <mr.nuke.me@gmail.com>
