Subject: [PATCH 2/5] m68knommu: make 523x CPU reset register addressing consistent
Date: Tue, 28 Feb 2012 13:58:19 +1000	[thread overview]
Message-ID: <1330401502-26250-2-git-send-email-gerg@snapgear.com> (raw)
In-Reply-To: <1330401502-26250-1-git-send-email-gerg@snapgear.com>

From: Greg Ungerer <gerg@uclinux.org>

If we make all MCF_RCR (CPU reset register) addressing consistent across all
ColdFire CPU family members that use it then we will be able to remove the
duplicated copies of the code that use it.
