[PATCH] m68knommu: extract common timer code for 68328 processor
Rework the 68x328 configuration and setup code. All 68x328 varient share the same timer hardware, so extract that into its own file, instead of keeping copies in each processors setup code. Signed-off-by: Greg Ungerer <gerg@uclinux.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
