If multiple VGA-compatible legacy graphic cards decode the IO range
3B0-3BB, 3C0-3DF and MEM range A00000-BFFFF.
Windows 7 complain a resource conflict, so only one VGA card can
works at the same time.
There is a discussion in coreboot mail list before,
please reference thread: "how to prevent legacy resource conflictwith multipleVGA cards"
http://www.coreboot.org/pipermail/coreboot/2010-October/061508.html
Linux using VGA Arbiter module(vgaarb) to resolve this resource conflict,
Please see the following linux dmesg log, more information can be found in
Linux source dir Documentation/vgaarbiter.txt.
But it seems that windows don't dealwith this conflict.
~# dmesg | grep -i vgaarb
[ 0.774076] vgaarb: device added: PCI:0000:00:01.0,decodes=io+mem,owns=io+mem
[ 0.776065] vgaarb: device added: PCI:0000:01:00.0,decodes=io+mem,owns=none,l

[ 0.784049] vgaarb: bridge control possible 0000:01:00.0
[ 0.788050] vgaarb: bridge control possible 0000:00:01.0
For the second legacy graphic device, coreboot already disabled the
IO and MEM decode in function set_vga_bridge_bits().
But it will be enabled again in function pci_set_resource(),
if the second legacy vga-compatible graphic device take any IO/MEM resources.
Following log printed by enable_resources() shows the problem:
...snip...

PCI: 00:01.0 subsystem <- 1022/1410
PCI: 00:01.0 cmd <- 07 <== The first graphic device

done.
...snip...
The IO & MEM decoding on the second vga graphic device should be disabled.
Please reference PCI spec. section 3.10 in detail.
set_vga_bridge_bits() would do this work for us, it did the right thing,
but was put to the wrong place, the setting would be overwritten by
assign_resources() later.
In order to make sure the set_vga_bridge_bits() setting not be
overwritten by others, moving the call of set_vga_bridge_bits()
to the end of dev_configure(), instead of at the beginning.
This patch resolved the dual graphic cards resource conflict in windows7,
multiple vga-compatible graphic cards can work together in windows7.

This allows to add a PCI ID mapping function for option roms so that the same

A function to implement such a mapping could look like this (or anything else
appropriate):

Originally brought up by Sven Schnelle in March 2011
http://patchwork.coreboot.org/patch/2801/http://www.coreboot.org/pipermail/coreboot/2011-March/064277.html
On some mainboards it may be neccessary to reset early during resume
from S3 if the SLFRCS register indicates that a memory channel is not
guaranteed to be in self-refresh.
On other mainboards, such as Lenovo X60 and T60, the check always
creates false positives, effectively making it impossible to resume.
The SLFRCS register is documented on page 197 of
Mobile Intel® 945 Express Chipset Family Datasheet
Document Number: 309219-006
which is publically available, and the register indicates if a memory
channel is guaranteed to be in self-refresh mode (if bit = 1), or that
a memory channel *may or may not be* in self-refresh mode (if bit = 0).
The register can thus only be used to positively learn that memory is
in self-refresh. It is not known for sure that memory is *not* in
self-refresh. The register is reset by the PWROK signal, which *should*
go low during S3, and go high again when resuming, so it is unsurprising
that SLFRCS has already been cleared when we read the register.
Sven's measurements of the CKE signal on a ThinkPad shows that memory
remains in self-refresh indefinitely, until coreboot re-initializes the
memory controller, even when SLFRCS bits were = 0.
Boards which require a warm reset when SLFRCS bits are cleared must now
explicitly enable the check in the mainboard Kconfig file.
This commit selects the new option in all existing i945 mainboards.
A follow-up commit will remove the option for ThinkPads.
