[PATCH] AVR32: add io{read,write}{8,16,32}{be,} support
A number of new drivers require io{read,write}{8,16,32}{be,} family of io
operations. These are provided for the AVR32 by this patch in the form of
a series of macros.
Access to the (memory mapped) io space through these macros is defined to
be little endian only as little endian devices (such as PCI) are the main
consumer of IO access. If high speed access is required,
io{read,write}{16,32}be macros are supplied to perform native big endian
access to this io space.
