m68k,m68knommu: merge header files
Merge header files for m68k and m68knommu to the single location: arch/m68k/include/asm The majority of this patch was the result of the script that is included in the changelog below. The script was originally written by Arnd Bergman and exten by me to cover a few more files. When the header files differed the script uses the following: The original m68k file is named <file>_mm.h [mm for memory manager] The m68knommu file is named <file>_no.h [no for no memory manager] The files uses the following include guard: This include gaurd works as the m68knommu toolchain set the __uClinux__ symbol - so this should work in userspace too. Merging the header files for m68k and m68knommu exposes the (unexpected?) ABI differences thus it is easier to actually identify these and thus to fix them. The commit has been build tested with both a m68k and a m68knommu toolchain - with success. The commit has also been tested with "make headers_check" and this patch fixes make headers_check for m68knommu.

2 * linux/include/asm-m68k/io.h
3 *
4 * 4/1/00 RZ: - rewritten to avoid clashes between ISA/PCI and other
5 * IO access
6 * - added Q40 support
7 * - added skeleton for GG-II and Amiga PCMCIA
8 * 2/3/01 RZ: - moved a few more defs into raw_io.h
9 *
10 * inX/outX should not be used by any driver unless it does
11 * ISA access. Other drivers should use function defined in raw_io.h
12 * or define its own macros on top of these.
13 *
14 * inX(),outX() are for ISA I/O
15 * isa_readX(),isa_writeX() are for ISA memory
