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