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

Pull m68knommu updates from Greg Ungerer:
 "The bulk of the changes are generalizing the ColdFire v3 core support
  and adding in 537x CPU support.  Also a couple of other bug fixes, one
  to fix a reintroduction of a past bug in the romfs filesystem nommu
  support."

* 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu:
  m68knommu: enable Timer on coldfire 532x
  m68knommu: fix ColdFire 5373/5329 QSPI base address
  m68knommu: add support for configuring a Freescale M5373EVB board
  m68knommu: add support for the ColdFire 537x family of CPUs
  m68knommu: make ColdFire M532x platform support more v3 generic
  m68knommu: create and use a common M53xx ColdFire class of CPUs
  m68k: remove unused asm/dbg.h
  m68k: Set ColdFire ACR1 cache mode depending on kernel configuration
  romfs: fix nommu map length to keep inside filesystem
  m68k: clean up unused "config ROMVECSIZE"
