+- * 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.
