[coreboot] Quick CK804 PCI device numbering question

[Timothy Pearson]

All,

I have been working on porting Coreboot to a new CK804-based K10 
mainboard; it warm boots but will not cold boot due to IRQ/MSI 
configuration issues.

While tracing the IRQ problem I noticed that the CK804 PCI function 
numbers change from the proprietary BIOS to Coreboot:

Proprietary:
-[0000:00]-+-00.0  NVIDIA Corporation CK804 Memory Controller [10de:005e]
            +-01.0  NVIDIA Corporation CK804 ISA Bridge [10de:0051]
            +-01.1  NVIDIA Corporation CK804 SMBus [10de:0052]
            ...etc...

Coreboot:
-[0000:00]-+-01.0  NVIDIA Corporation CK804 Memory Controller [10de:005e]
            +-02.0  NVIDIA Corporation CK804 ISA Bridge [10de:0051]
            +-02.1  NVIDIA Corporation CK804 SMBus [10de:0052]

This, in turn, causes Linux to not detect the CK804 root bridge.

Has anyone else seen this with the CK804 chipset?  Is there a magic 
register somewhere that configures the CK804 to use the "correct" PCI 
function numbers?

The only pertinent quirk of this mainboard is that Asus put the CK804 on 
HT link 1, not 0 or 2 as is more common.

Thanks!
