From 76148ab8b79e0b40107a96f97e7fd7a0f1f732a1 Mon Sep 17 00:00:00 2001 From: Greg Ungerer Date: Tue, 17 Apr 2012 15:35:01 +1000 Subject: m68knommu: move the 528x platform code into the common ColdFire code directory All these separate directories for each ColdFire CPU SoC varient seems like overkill. The majority of them only contain a single small config file. Move these into the common ColdFire code directory.
