m68knommu: platform code merge for 68000 core cpus
This patch merges all 68000 core cpus into one directory. There is a lot of common code in the 68328, 68EZ328 and 68VZ328 directories. This will also facilitate easy development of support for original stand alone MC68000 CPU machines. Signed-off-by: Luis Alves <ljalvs@gmail.com> Signed-off-by: Greg Ungerer <gerg@uclinux.org>
