RE: PCI driver on EB8347

Kumar,

         Here is lspci -v from my P2P system. In case you have any suggestion do let me know. I appreciate your help

00:11.0 PCI bridge: Texas Instruments PCI2050 PCI-to-PCI Bridge (rev 02) (prog-if 00 [Normal decode])
        Flags: bus master, 66Mhz, medium devsel, latency 0
        Bus: primary=00, secondary=01, subordinate=01, sec-latency=0
        I/O behind bridge: 0000f000-0000ffff
        Memory behind bridge: 9e000000-9fffffff
        Prefetchable memory behind bridge: 000000009df00000-000000009df00000
        Capabilities: [dc] Power Management version 2

01:01.0 Non-VGA unclassified device: Texas Instruments: Unknown device 9065 (rev 01)
        Flags: bus master, 66Mhz, medium devsel, latency 128, IRQ 18
        Memory at 9fc00000 (32-bit, prefetchable) [size=4M]

         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.
