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

Pull m68knommu arch update from Greg Ungerer:
 "Quite a varied set of changes this time.
   - A little more merge cleanup, this time the assembler entry code.
   - New sub-architecture support for the ColdFire 5251/5253 and 5441x
     CPU families.
   - Specific clk support code for the ColdFire 520x and 532x CPU
     familes.
   - Refactoring of the ColdFire GPIO support.
   - PCI bus support for some ColdFire CPUS that have PCI hardware (54xx
     family).  This showed up a few problems with ColdFire cache,
     allocating coherent memory and bi-directional DMA support.  Fixes
     for those too."

* 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu: (21 commits)
  m68k: allow PCI bus to be enabled for ColdFire m54xx CPUs
  m68k: add PCI bus code support for the ColdFire M54xx SoC family
  m68k: add IO access definitions to support PCI on ColdFire platforms
  m68k: add PCI bus support definitions for the ColdFire M54xx SoC family
  m68k: common PCI support definitions and code
  m68k: add support for DMA_BIDIRECTIONAL in dma support functions
  m68k: fix ColdFire clear cache operation
  m68k: use simpler dma_alloc_coherent() for ColdFire CPUs
  m68knommu: platform support for 8390 based ethernet used on some boards
  m68knommu: Add clk definitions for m532x.
  m68knommu: Add clk definitions for m520x.
  m68knommu: Add rtc device for m5441x.
  m68knommu: add definitions for the third interrupt controller on devices that don't have a third interrupt controller.
  m68knommu: Add support for the Coldfire m5441x.
  m68knommu: use MCF_IRQ_PIT1 instead of MCFINT_VECBASE + MCFINT_PIT1
  coldfire-qspi: Add support for the Coldfire 5251/5253.
  m68knommu: Add support for the Coldfire 5251/5253
  m68knommu: refactor Coldfire GPIO not to require GPIOLIB, eliminate mcf_gpio_chips.
  m68k: merge the MMU and non-MMU versions of the entry.S code
  m68k: use jbsr to call functions instead of bsrl

- *	Define macros to ease the pain of setting up the GPIO tables. There

- *	in the layout and number of bits in each ColdFire part, but the macros
- *	take all that in.
+ * The Freescale Coldfire family is quite varied in how they implement GPIO.
+ * Some parts have 8 bit ports, some have 16bit and some have 32bit; some have
+ * only one port, others have multiple ports; some have a single data latch
+ * for both input and output, others have a separate pin data register to read
+ * input; some require a read-modify-write access to change an output, others
+ * have set and clear registers for some of the outputs; Some have all the
+ * GPIOs in a single control area, others have some GPIOs implemented in
+ * different modules.
  *
- *	Firstly is the conventional GPIO registers where we toggle individual
- *	bits in a register, preserving the other bits in the register. For
- *	lack of a better term I have called this the slow method.
+ * This implementation attempts accommodate the differences while presenting
+ * a generic interface that will optimize to as few instructions as possible.
