From c8c5fc266e4499e283c293ccb972863156aa4134 Mon Sep 17 00:00:00 2001 From: Anton Vorontsov Date: Thu, 29 May 2008 18:14:56 +0400 Subject: [PATCH] 83xx/85xx: further localbus cleanups Merge mpc85xx.h's LBC defines to fsl_lbc.h. Also, adopt ACS names from mpc85xx.h, so ACS_0b10 renamed to ACS_DIV4, ACS_0b11 to ACS_DIV2.
