Merge tag 'm68knommu-for-v6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu

Pull m68knommu updates from Greg Ungerer:
 "A few changes, most of them related to fixing warnings when compiling
  with "W=1". These follow up Geert's recent changes for M68K for this
  too. These ones complete the fixes for the nommu and ColdFire specific
  code.

  Also a couple of other fixes to improve ROM default addressing and
  compiling for the Cleopatra boards.

  Summary:

   - improve default Kconfig ROM section settings

   - fix compilation for some Cleopatra boards

   - fixes and cleanups for warnings compiling with 'W=1'"
