From: Greg Ungerer Date: Tue, 17 Apr 2012 05:25:44 +0000 (+1000) Subject: m68knommu: move the 520x platform code into the common ColdFire code directory X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=a654730ec1cd5b4bc170e7ae7ee358f2a7a554c2;p=deliverable%2Flinux.git m68knommu: move the 520x 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.
