I don't yet, but it'd be great if you were willing to test them out,
so I'll set one up.

While this is on your mind, I'm dubious about the pci_enable_bridges()
call in lba_driver_probe() and the pci_bus_assign_resources() call in
dino_probe().  These stand out as exceptions because no other arches
do that.

If they weren't there, both places could use pci_scan_root_bus() like
most other arches.
