From 2146cf56821c3364786ca94a7306008c5824b238 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Wed, 19 Dec 2007 01:18:15 -0600 Subject: Reworked FSL Book-E TLB macros to be more readable The old macros made it difficult to know what WIMGE and perm bits were set for a TLB entry. 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.
