[oc] PCI any one?

Hi

I just got the PCI card I'm designing to talk to SDRAM
across the PCI bus from a host computer.
take a look at:
http://www.openh.org/projects/ERPCN01
(see images section at the bottom)

A PCI question...
The PCI controller chip I'm using defaults my SDRAM window (BAR0) to 16MB
wide.
I can easily reprogram the window size in the chip to the full size
of my memory which is 32Mbytes.
The problem is: How do I notify the PCI host controller about this
change in size. It may have already allocated the memory
above the current window to anouther device and cause
conflict.

thanks
Carl
