Merge tag 'sh-for-v6.7-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/glaubitz/sh-linux

Pull sh updates from John Paul Adrian Glaubitz:
 "While the previously announced patch series for converting arch/sh to
  device trees is not yet ready for inclusion to mainline and therefore
  didn't make it for this pull request, there are still a small number
  changes for v6.7 which include one platform (board plus CPU and driver
  code) removal plus two fixes.

  The removal sent in by Arnd Bergmann concerns the microdev board which
  was an early SuperH prototype board that was never used in production.
  With the board removed, we were able to drop the now unused code for
  the SH4-202 CPU and well as the driver code for the superhyway bus and
  a custom implementation for ioport_map() and ioport_unmap() which will
  allow us to simplify ioport handling in the future.

  Another patch set by Geert Uytterhoeven revives SuperH BIOS
  earlyprintk support which got accidentally disabled in
  e76fe57447e88916 ("sh: Remove old early serial console code V2"), the
  second patch in the series updates the documentation.

  Finally, a patch by Masami Hiramatsu fixes a regression reported by
  the kernel test robot which uncovered that arch/sh is not implementing
  arch_cmpxchg_local() and therefore needs use __generic_cmpxchg_local()
  instead"
