SubjectRe: New PCI code for Alpha
   Date: 	Sun, 23 Aug 1998 15:36:18 -0700
From: Richard Henderson <rth@cygnus.com>

The cleanest thing would be for the kernel itself to never ever use
pcibios_*_config_*, but instead always use pci_*_config_*. With
the later, I still have the full device structure, and I can walk
back up to dev->bus->sysdata and find out what I need to know. But
I figured it was way too close to 2.2 for such a change to be
considered.

I have several ideas now for 2.3 how to rearrange things to make
multi-bus machines happier.

As for the art of independant discovery, we had brought up these
issues quite some time ago wrt. sparc64/pci machines. As you can see
this proposed scheme never happened, and thus we use the same hacks
for multi-bus PCI machines as you are now on the Alpha.

It would be nice to have it in 2.3.x
