m68knommu: create common DMA table for ColdFire CPUs Move the ColdFire DMA address table into its own file, and out of each of the different CPU config files. No need to have a copy of it in each of the config setup files. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

m68knommu: move ColdFire DMA register addresses to per-cpu headers The base addresses of the ColdFire DMA unit registers belong with all the other address definitions in the per-cpu headers. The current definitions assume they are relative to an MBAR register. Not all ColdFire CPUs have an MBAR register. A clean address define can only be acheived in the per-cpu headers along with all the other chips peripheral base addresses. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
