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@e000a000 ranges:
MEM 0x00000000a0000000..0x00000000afffffff -> 0x00000000a0000000
IO 0x00000000e2800000..0x00000000ea7fffff -> 0x0000000000000000
/pcie@e000a000: PCICSRBAR @ 0xfff00000
Is 0xe2800000 the iobase_phys of the PCI bridge?
So any suggestion is appreciated!
regards,
wolfking.
