Not much more efficient, given the almost zero odds of having more than five mmio handlers that can skip p2m lookup. The only better performant option seems open-coding. Given the sensitivity of the path, I'd say stick with the original plan with two open coded if's (blatant backtrack!) Let me know if you'd rather we follow the route I laid out here.
Thanks Andres
