Specifying parallel I/O ports has whole registers is really
uncomfortable: If for example one would like to write a value to a
parallel I/O port, then he'd need to read the data register first, then
mask off all irrelevant bits, and then write the shifted value to this
register. The pario command does this job in a much more comfortable
way.
Again - we can keep this command in our boards' common code, but I think
it would be a pity, as I think this functionality can be useful for many
other CPU types as well.
