+/*
+ * 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/readX/writeX should not be used by any driver unless it does
+ * ISA or PCI access. Other drivers should use function defined in raw_io.h
+ * or define its own macros on top of these.
+ *
+ *    inX(),outX()              are for PCI and ISA I/O
+ *    readX(),writeX()          are for PCI memory
+ *    isa_readX(),isa_writeX()  are for ISA memory
+ *
+ * moved mem{cpy,set}_*io inside CONFIG_PCI
