Cronyx/Tau is not compatible with other devices based on hd64570, cause
we have some
additional logic. For pci devices we use another controllers (PEB 20534
(cp) and Munich 32(ce)).
Those devices are also incompatible with other devices based on those
controllers because of
additional logic. So I can assure that ctau driver wouldn't support
other devices in near future.
If we decide to make a new device based on this controller, I'll choose
another names for it.
