* IO port access primitives
* -------------------------
*
* The ARM doesn't have special IO access instructions; all IO is memory
* mapped. 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.
