Re: PCI driver on EB8347

Kumar, Liu
                  I was able to resolve problem. Problem was in PCI card 
firmware and not in Linux Kernel  or driver.

                             Thanks for your help.
Regards,

         Thanks IRQ problem is resolved. As  pointed out it was 
problem with IRQ IDSEL mapping. Mapping needs to be different on Eval 
board I'm using and our custom design. But my driver is still not 
working on our custom design. PCI device doesn't receive any messages 
from MPC8347 on our custom design mother board which uses pci-bridge 
where as it works fine on Eval board which doesn't use PCI bridge.

                        I guess problem lies at the kernel level and 
not the driver. Any tips apart from IDSEL IRQ settings at kernel 
level what else I need to change when I move from 1 mother board to 
another.  My PCI  devices do get base address 0 and 1 allocated 
properly by the OS. But when I try to write any messages on those 
addresses PCI device doesn't see them

Is the bridge getting configured correctly?  An lspci output would be 
helpful from your system with the P2P bridge.
