Good. But we still have annoying warning about "no compatible window".

Please try attached patch that support 64bit pci mem space for sparc.

BTW, looks like you still do not have   CONFIG_PCI_DEBUG=y in your .config.
otherwise we should more verbose print out.
Or did you have DYNAMIC_DEBUG enabled ?
If it is that case, can you remove that?

Thanks
