From b7dcf7fe7c3060db38fc625efffad5965a5c6d8a Mon Sep 17 00:00:00 2001 From: Greg Ungerer Date: Fri, 1 Feb 2008 17:38:24 +1000 Subject: [PATCH] m68knommu: fix 528x ColdFire cache settings Fix problems with the 528x ColdFire CPU cache setup. Do not cache the flash region (if present), and make the runtime settings consistent with the init setting.
