Why are these "RFC"?

I guess you don't want them merged because you are not thinking that
they are good enough?  What needs to be done on them that you are
sending them out now?

Please convert this to a schema. See

Bindings are for h/w blocks, not drivers.

Is this really all one h/w block.

FlexNoC is an interconnect, right? Is there more to it than just 
perfmon?
