Hi,

It seems that I have forgotten to include a small patch to make the
driver compile. Apply the following small patch and it should compile after:

Index: pcireg.h

Unfortunately, even with that you'll find that the driver doesn't do
much so far. It's just probing for the HDA controller and then tries to
scan for some child devices.

I haven't got the chance to put as much efforts into this lately as I
would have liked to do but it's progressing. The driver that I have in
my local tree now really probe for child devices using newbus and tries
to attach drivers to them. I'll try to make it available within a few
days in case anybody wants to look at it.

Regards,

Steph
