Hello,

I am attempting to setup the pci_controller device for my target board. PCI Type 0 configuration addresses are directly mapped into local memory so I am not using the indirect method. I have routed everything to be dword accessed like board/dave/common/pci.c:189 It appears that the pci_hose_scan_bus uses type 1 addresses when scanning the pci bus. In my read_dword: and write_dword I convert the dev (type 1 address) into an appropriate type 0 address.

Is this the correct method for doing type0 scanning ?

In addition, the ixp2800 processor will data abort when scanning a type 0 address that is not present. In our simple bootloader we implemented the data abort handler to catch these exceptions and continue to scan. I have not been able to find an example in the uboot code of a data abort that is anything but fatal.

Has anyone else run into this ?

Thanks.
