Possibly, though it may not be the best idea to express every single
aspect of intercomponent integration via qdev -- maybe that's best left
for things that are reasonably user-tweakable. If CCSR size is user
tweakable, it would be somewhere other than the PCI controller.
It depends. Qdev properties are basically object constructor
parameters. So if you were weiting C++ code and would have a
constructor that gets the size as argument, it would end up being
modeled as qdev property.
If however actual functionality differs, thus you would in OO speech
create a subclass / child class, then you are better off creating a
new device struct.
In this case, I'm not sure. They are different devices really, but
are close enough that the differences could be expressed through qdev
properties.
