Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu

Pull m68knommu updates from Greg Ungerer:
 "This one has a major restructuring of the non-mmu 68000 support.

  It merges all the related SoC types that use the original 68000 cpu
  core internally so they can share the same core code.  It also allows
  for supporting the original stand alone 68000 cpu in its own right.

  There is also a generalization of the clock support of the ColdFire
  parts, some merging of common ColdFire code, and a couple of bug fixes
  as well."

* 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu:
  m68knommu: modify clock code so it can be used by all ColdFire CPU types
  m68knommu: add clock definitions for 54xx ColdFire CPU types
  m68knommu: add clock definitions for 5407 ColdFire CPU types
  m68knommu: add clock definitions for 5307 ColdFire CPU types
  m68knommu: add clock definitions for 528x ColdFire CPU types
  m68knommu: add clock definitions for 527x ColdFire CPU types
  m68knommu: add clock definitions for 5272 ColdFire CPU types
  m68knommu: add clock definitions for 525x ColdFire CPU types
  m68knommu: add clock definitions for 5249 ColdFire CPU types
  m68knommu: add clock definitions for 523x ColdFire CPU types
  m68knommu: add clock definitions for 5206 ColdFire CPU types
  m68knommu: add clock creation support macro for other ColdFire CPUs
  m68k: fix unused variable warning in mempcy.c
  m68knommu: make non-MMU page_to_virt() return a void *
  m68knommu: merge ColdFire 5249 and 525x definitions
  m68knommu: disable MC68000 cpu target when MMU is selected
  m68knommu: allow for configuration of true 68000 based systems
  m68knommu: platform code merge for 68000 core cpus
