Where does this stop? Do we start doing the same for all different kinds 
of buses, and all kinds of firmware? 

In other words, instead of having <n> different buses all know about <m>
different kinds of firmware information that they really have nothing else
to do with, it's much better to just have the <m> different kinds of 
firmware information export their own information.

It just sounds _wrong_ to have the PCI layer have knowledge of OF. It has 
nothing to do with OF. For OF information, you should go to the /sys/of 
tree, which has the information that OF knows about (which may, of course, 
then include the information about PCI devices).
