[coreboot] lspci output difference between Commercial BIOS and coreboot

[Ken.Fuchs at bench.com]

I have an nVidia CRB system that generates significantly
difference lspci output depending on whether the Commercial
BIOS or LinuxBIOS (coreboot) is used.

--- Summary of lspci output differences ---

When using LinuxBIOS (coreboot), the PCI video card doesn't
appear.  When I using the Commercial BIOS, the video card is
clearly identified as:
 
01:06.0 VGA compatible controller: Tseng Labs Inc ET6000 (rev 30)

The Comm. BIOS 00:18-19.x remains LinuxBIOS 00:18-19.x.

The Comm. BIOS 00:00-0e.x becomes LinuxBIOS 01:00-0e.x,
with some device # changes and one function # change.

The Comm. BIOS 80:00-0e.x becomes LinuxBIOS 02:00-0e.x,
but LinuxBIOS has the following additional entries:

02:01.1 SMBus: nVidia Corporation CK804 SMBus (rev a2)
02:01.2 Memory controller: nVidia Corporation: Unknown device 005f (rev
        a3)
02:0a.0 Ethernet controller: nVidia Corporation CK804 Ethernet
        Controller (rev a3)

--- Are these differences OK? ---

lspci output for both LinuxBIOS and Phoenix BIOS appears
after my sig.

It is confusing that LinuxBIOS (coreboot) and Phoenix BIOS
are using different PCI bus, device and function numbers in
some cases as detailed above.  I always assumed that didn't
matter, but now I'm not so positive.  Does it really matter?

Sincerely,

Ken Fuchs
