It can also bee @foo,bar, it doesn *have* to match the exact content of
the reg property first entry. In fact it's not uncommon to use a 64-bit
value here on 64-bit processors and pci uses a different encoding scheme
(on real OFW at least) where they typically do @dev,fn

Yes, the fact that the unit address is not something deterministic is
and has always been a major PITA though.

Cheers,
Ben.
