-- * IO port access primitives
-- * -------------------------

-- * The AVR32 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.
-- *
-- * 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.
