From 5b2e6555ac3eb58a4e5eb5020471df08f0c42c01 Mon Sep 17 00:00:00 2001 From: Greg Ungerer Date: Tue, 2 Nov 2010 12:05:29 +1000 Subject: [PATCH] m68knommu: make Coldfire 548x support more generic The ColdFire 547x family of processors is very similar to the ColdFire 548x series. Almost all of the support for them is the same. Make the code supporting the 548x more gneric, so it will be capable of supporting both families. For the most part this is a renaming excerise to make the support code more obviously apply to both families.
