Re: forcing pci device start address ?

From: Neil Wilson <hidden>

Ok, I see the horrible mess they put you in.  Those !@$!# hardware
guys. :-/
Here's the basic layout:  you can use pci_auto like the other 7xx/74xx
embedded ports and constrain the I/O and Mem range so as to not conflict
with the PCI-wannabe devices your hardware guys spit out.  You are
writing custom drivers so you just depart from the Linux standard of
ioremaping or in*/out*ing resources and use your hardcoded addresses.
You could complicate things by manually adding the devices to the
PCI global list and creating resources but there is no value in that
for a custom design like this...you could boast about it to your
fellow engineers if you like though. :)

Thanks for your help, I will start looking at this when I get in tomorrow.

Do you happen to know of a driver example in one of the kernel trees or
elsewhere that implements this hardcoded address business that I can learn
from ?

Thanks.

Neil
