From 4e63df300f05df2eb3ee87deed043a718ffc6a4e Mon Sep 17 00:00:00 2001 From: Becky Bruce Date: Thu, 17 Jun 2010 11:37:21 -0500 Subject: mpc85xx: tlb.c cleanups Extract the operation to read a tlb into a function - we will need this later to print out the tlbs, and there's no point in duplicating the code. Create a TSIZE_TO_BYTES macro to deal with the conversion from the MAS field to an actual size instead of duplicating this in code. There are a few misc other minor cleanups.
