Linux also needs the MMCONF area to be reserved either in E820 or
as an ACPI motherboard resource or it will not enable MMCONFIG
and the extended pcie configuration area will be unaccessible:
This patch adds the IORESOURCE_RESERVE flag to the APIC and MMCONF
resource flags to do this.
I also added a new resource for the mapped bios rom area just below 4GB.
I'm not sure if the choice for the index parameter of new_resource()
is correct though.
Note that the bios rom decode is enabled in
src/southbridge/via/vt8237r/vt8237r_early_smbus.c
for the whole 4MB area (even though the comment says 1MB).
Ruik: I extended the flash range to 16MB (This is what VT8237S can decode)
Remove the MMCONFIG region reserve in the mainboard file (this patch makes it obsolete)
