can't access PCIe card under sbc8548

hi, Herrenschmidt
 Thanks for replying to this topic!

The HW is OK. If I plug this card into another ppc board: mpc86641-hpcn,
it works fine.

Would you mind telling me at what position should I add the printk?
I can only print pci_iomap's return address which is mentioned in 
the previous mail, it is 0xfc7fc000. The following is part of the
linux boot message:

PCI host bridge /pcie at e000a000  ranges:
 MEM 0x00000000a0000000..0x00000000afffffff -> 0x00000000a0000000 
  IO 0x00000000e2800000..0x00000000ea7fffff -> 0x0000000000000000
/pcie at e000a000: PCICSRBAR @ 0xfff00000

 Is 0xe2800000 the iobase_phys of the PCI bridge?

So any suggestion is appreciated!

regards,
wolfking.
