From 7f72b47cedd1efc301576ff1050ec0a26c57eb48 Mon Sep 17 00:00:00 2001 From: Greg Ungerer Date: Tue, 28 Apr 2009 14:13:21 +1000 Subject: m68knommu: fix system reset for ColdFire 527x family The sofwtare reset control for the 527x ColdFire family is based on the same Reset Control Unit as the 528x ColdFire family. So use the same reset code for both.
