Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu
Pull m68knommu tree from Greg Ungerer: "More merge and clean up of MMU and non-MMU common files, namely signal.c and dma.c. There is also a simplification of the ColdFire GPIO setup tables. Using a couple of simple macros we make the init tables really small and easy to read, and save a couple of thousand lines of code. Also a move of all the ColdFire subarch support files into the existing coldfire directory. The sub-directories just ended up duplicating Makefiles and now only contain really simple pieces of code. This saves quite a few lines of code too. As always a couple of bugs fixes thrown in too. Oh and a new defconfig for the ColdFire platforms that support having the MMU enabled." * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu: (39 commits) m68k: add a defconfig for the M5475EVB ColdFire with MMU board m68knommu: unaligned.h fix for M68000 core m68k: merge the MMU and non-MMU versions of the arch dma code m68knommu: reorganize the no-MMU cache flushing to match m68k m68knommu: move the 54xx platform code into the common ColdFire code directory m68knommu: move the 532x platform code into the common ColdFire code directory m68knommu: move the 5407 platform code into the common ColdFire code directory m68knommu: move the 5307 platform code into the common ColdFire code directory m68knommu: move the 528x platform code into the common ColdFire code directory m68knommu: move the 527x platform code into the common ColdFire code directory m68knommu: move the 5272 platform code into the common ColdFire code directory m68knommu: move the 5249 platform code into the common ColdFire code directory m68knommu: move the 523x platform code into the common ColdFire code directory m68knommu: move the 520x platform code into the common ColdFire code directory m68knommu: move the 5206 platform code into the common ColdFire code directory m68knommu: simplify the ColdFire 5407 GPIO struct setup m68knommu: simplify the ColdFire 532x GPIO struct setup m68knommu: simplify the ColdFire 5307 GPIO struct setup m68knommu: simplify the ColdFire 528x GPIO struct setup m68knommu: simplify the ColdFire 527x GPIO struct setup ...
