Hi all,
in the old arch/ppc tree, there was a function called pq2ads_setup_pci()  
that set up PCI regs for 8272xx, in m82xx_pci.c. I was wandering, where  
are these registers configured now in arch/powerpc? I can't seem to find  
these code now.

It's done by the firmware or the bootwrapper.

Also, I can see that now bus 0, dev 0 (which I think represents the host  
bridge, right?) is now excluded using pq2_pci_exclude_device, but it  
wasn't in older code. Why is that?

The older code probably either excluded all host bridges by class, or
just lived with the error message that gets printed on boot.
