Hi.

I'm trying to port this version of linux on our board that is similar to ADI BRH \
board but different in a sense that it will accomodate multiple numbers of compact \
PCI type devices.

Btw, is it missing/not completed or I don't know it well? What I mean is, inside the \
brh_pci_init function, there is no pcibios_allocate_bus_resources() and \
pcibios_allocate_resources() function calls on this patch. Our board will use compcat \
PCI type PCMCIA card, hence I guess they are necessary.

Anyway, I tried to boot the system in both cases: 1)run the code as it is 2)run the \
code with the inclusion of those two functions above. But, in the first case, it has \
some problems when I run the 'cardmgr' on the prompt, and in the second case, it has \
some problems on the bootup time. Here I attached the boot sequence on the second \
case. I guess the problem is 'can not allocate resource region' part. If somebody \
know it, please help me out.
