I thought about something similar 2 months ago, but then realized
MicroBlaze cores can be synthetized in 64-bit, and IIRC there is
not much missing (I'd say effort would be to add 20% more of what
we currently have). Just wanted to mention before taking the
decision to restrict to 32-bit. OTOH if there are no plan for
adding 64-bit support at AMD, then I'm more than happy to simplify
by considering only 32-bit.
