Thanks Greg for reply. I am looking for PPC first and hopefully other arch as I continue. Also, I am trying to have both MMU and noMMU because my understanding is noMMU might give better performance and better timing predictability (no VM exceptions for dynamic memory allocation). Definitely great Linux distribution to work on.
