Since there don't seem to be any examples of this in the tree: do you have a format preference?  For the rest of the compatible lists, I'm using something like: xlnx,ipname-version.  So for the microblaze, I'd prefer something like:

xlnx,microblaze-6.00.b

For the powerpc, either ibm,ppc405 or ibm.ppc-405 would seem to be more in character than PowerPC,405.

I'm trying to encourage people to move to naming cpu nodes simply
"cpu@XX", with the type of core in "compatible" instead - in keeping
with the generic names convention used elsewhere.  I think this will
make your generator simpler, too.
