PCI Express error on MPC8641D-HPCN

PCI Express error on MPC8641D-HPCN

[Reinhard Weiss]

Hi,

I try to get 2.6.25.6 running on Freescale's MPC8641D-HPCN (Processor is revision 1), but somehow the PCI express controller setup fails:

PCI: Probing PCI hardware
PCI: 0000:00:00.0: class b20 doesn't match header type 01. Ignoring class.
PCI: 0001:02:00.0: class b20 doesn't match header type 01. Ignoring class.
PCI: Closing bogus Apple Firmware region 1 on bus 0x03
PCI: Closing bogus Apple Firmware region 2 on bus 0x03
PCI: Cannot allocate resource region 0 of device 0000:01:1d.0, will remap
PCI: Cannot allocate resource region 1 of device 0000:01:1d.1, will remap
PCI: Failed to allocate I/O resource #0:100@1000 for 0000:01:1d.0
PCI: Failed to allocate I/O resource #1:100@1000 for 0000:01:1d.1
PCI: not setting up bridge 0000:00:00.0 for bus 1
PCI: Enabling device 0000:00:00.0 (0106 -> 0107)
PCI: not setting up bridge 0001:02:00.0 for bus 3
PCI: Enabling device 0001:02:00.0 (0106 -> 0107)

- PCIe worked with 2.6.20.7 on this board, but unfortunately SMP support was not ready then. 
- on MPC8610-HPCD, PCIe works with 2.6.25.6, so I wonder what could be the difference.

Any ideas?

Best regards,
Reinhard

I'm working with this board and I'm beginning to doubt that the pci 
express works well. You can see my problems in my previous posts in this 
mailing list sometimes ago.
