I suppose.   If we were needlessly pedantic, then perhaps
the libata-bmdma.c should be renamed to libata-sff.c,
and the libata-sff.c should be renamed libata-tf.c

But there's probably been a document or two since then,
where the SFF folks have documented the TF interfaces, too.

So.. whatever.  :)
