As far as your patch is concerned, you are essentially trying to use a true 32-bit processor (my definition being that it is not a 64-bit processor running in 32-bit mode), to address address more than 4GB of physical memory. I don't see how that is possible with just the MMU and TLB unless you are using chip selects and customm logic. -Steve -- Steven J. Hill - Embedded SW Engineer
