Greg,

I'm getting the following message from the kernel on an embedded  
ppc32
system:

PCI: Failed to allocate mem resource #9:100000@e0000000 for  
0000:00:00.0

The HW setup is a PCIe host controller and an e1000 NIC card.  It  
appears
that pci_bus_assign_resources() is trying to call  
pci_assign_resource() for
the ROM and the resource for the ROM is [100000:1fffff] where the  
PHB is
[c0000000:dfffffff].

It seems like the resno that pci_assign_resource is getting called  
with is
wrong and thus pci_update_resource() doesn't get called.

any ideas?

Nope, sorry, any help debugging this is appreciated, pci resource
allocation is "tricky" :)

I'm happy to debug, is the fact that the resno == 9 ok or does that  
seem wrong?
