From 1d47273d46925929f8f2c1913cd96d7257aade88 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Tue, 18 Dec 2007 23:21:51 -0600 Subject: Use FSL Book-E MMU macros from Linux Kernel Grab the FSL Book-E MAS register macros from Linux. Also added defines for page sizes up to 4TB and removed SHAREN since it doesnt really exist.

Actually use the bit masks for these items since they are only a single bit. Also moved the macros into mmu.h out of e500.h since they aren't specific to e500.
