- /*
- * 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
