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 here are to clean up the ColdFire 5441x SoC
  support so that it can run with MMU enabled. We have only supported it
  with MMU disabled up to now.

  There is also a few individual bug fixes across the ColdFire support
  code"

* 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu:
  m68k: let clk_disable() return immediately if clk is NULL
  m68knommu: convert printk(KERN_INFO) to pr_info()
  m68knommu: clean up uClinux boot log output
  m68k: generalize uboot command line support
  m68k: don't panic if no hardware FPU defined
  m68k: only generate FPU instructions if CONFIG_FPU enabled
  m68k: always make available dump_fpu()
  m68k: generalize io memory region setup for ColdFire ACR registers
  m68k: move ColdFire _bootmem_alloc code
  m68k: report correct FPU type on ColdFire MMU platforms
  m68k: set appropriate machine type for m5411x SoC platforms
  m68k: move CONFIG_FPU set to per-CPU configuration
  m68knommu: fix IO write size in nettel pin set
  m68knommu: switch to using IO access methods in WildFire board code
  m68knommu: fix early setup to not access variables
