It is almost more appropriate to use bus_space_{read,write} than using
memory mapped structures.  The bus macros will work for otherwise
unaligned thigns, while direct access won't.  Also, the
compiler/system may optimize things in strange ways that cause
problems.  Do yourself a big favor and don't go down this path.
