- *  IO port access primitives

- * Note that these are defined to perform little endian accesses
- * only.  Their primary purpose is to access PCI and ISA peripherals.
- *
- * Note that for a big endian machine, this implies that the following
- * big endian mode connectivity is in place, as described by numerious
- * ARM documents:
- *
- *    PCI:  D0-D7   D8-D15 D16-D23 D24-D31
- *    ARM: D24-D31 D16-D23  D8-D15  D0-D7
- *
- * The machine specific io.h include defines __io to translate an "IO"
- * address to a memory address.
- *
- * Note that we prevent GCC re-ordering or caching values in expressions
- * by introducing sequence points into the in*() definitions.  Note that
- * __raw_* do not guarantee this behaviour.
- *
- * The {in,out}[bwl] macros are for emulating x86-style PCI/ISA IO space.
