* m68k: add a defconfig for the M5475EVB ColdFire with MMU boardGreg Ungerer2012-05-201-0/+62
| | | | | | | Add a default configuration for the newly supported ColdFire CPUs running with MMU enabled. This is based on Freescales own M5475EVB demo board. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
* m68knommu: unaligned.h fix for M68000 coreLuis Alves2012-05-201-1/+1
| | | | | | | | | | | | | | This patch fixes unaligned memory access for the 68000 core based cpu's. Some time ago, my cpu (68000) was raising address/bus error's when mounting cifs shares (didn't bother to debug it at the time). After developing the MMC/SD card driver I was having the same issue when mounting the vfat fs. I've traced the issue down to the 'unaligned.h' file. (I guess nobody has ever used unaligned.h back in the 68328 'era'. Signed-off-by: Luis Alves <ljalvs@gmail.com> Signed-off-by: Greg Ungerer <gerg@uclinux.org>
* m68k: merge the MMU and non-MMU versions of the arch dma codeGreg Ungerer2012-05-203-209/+162
| | | | | | | | | | | | The majority of the m68k architecture dma code is the same, so merge the current separated files dma_no.c and dma_mm.c back into a single dma.c The main alloc and free routines are a little different, so we keep a single #ifdef based on CONFIG_MMU for them. All the other support functions are now identical. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Acked-by: Geert Uytterhoeven <geert@linux-m68k.org>
* m68knommu: reorganize the no-MMU cache flushing to match m68kGreg Ungerer2012-05-201-4/+28
| | | | | | | | | | | | | Introduce cache_push() and cache_clear() functions for the non-MMU m68k devices. With these in place we can more easily merge some of the common m68k arch code. In particular by reorganizing the __flush_cache_all() code and separating the cache push and clear functions it becomes trivial to implement the new cache_push() and cache_clear() functions.

Merge the two back into a single signal.c, and move some of the code around inside the file to minimize the number of #ifdefs required. Specificially we can group out the CONFIG_FPU and the CONFIG_MMU code. We end up needing a few other "#ifdef CONFIG_MMU" as well, but not too many.
