[U-Boot-Users] Help with mpc8540 pci

[CuiYW]

Hi,
    I am porting U-Boot to our custom MPC8540 board. But there are some problems on pci. Following is the boot message:

    ... ...
L2 cache enabled: 256KB

pci_bus_to_hose() failed

pci_bus_to_hose() failed

pci_bus_to_hose() failed

pci_bus_to_hose() failed

PCI Autoconfig: BAR 2, I/O, size=0x10, address=0xe2000010

... ...


    Sometimes, U-boot halted after the message: "PCI Autoconfig: I/O region: [e2000000-e2ffffff]".
         
         Somebody has the same problem? Could you please give me any advice?
