QEMU has pl031 and pl061 devices in addition to pl011, but no pl022
as far as I can tell.

That would have precedents in eg. PCI controllers, where the <model>
subelement contains the hypervisor-specific device name whereas
the 'model' attribute of the <controller> element contains a more
generic name...

You might have just convinced me :)

Of course that would lead to duplicated information in the existing
cases of ISA, USB and PCI, but I guess we can live with that.

Pino, any ideas about this?
