i don't believe i've changed the structure of anything.
and of course there's no reason you need to use the atom
stuff at all.  i just thought it might help with your problem.

fis.h is required because all the sata drivers need to format
fises and that code is centralized in libfis.  a fis is the sata
analogue to the ide register block.  now that there are
multiple sata drivers (at least in atom), it makes sense.
the alternative to the library is to copy the same code around
here and there.  that was the original approach, but it
resulted in too many bugs.
