Jeff, Tejun, what "sff" in the file name actually means? Isn't
it strange that the drivers lacking DMA support or not really
compliant with SFF-8038i have to link with this file?
Maybe it should be libata-tf and libata-bmdma, but sff (sans bmdma)
and bmdma is acceptable, hopefully, right?
What's sff sans bmdma?
Supposed to be TF interface. IIRC, the SFF term was first from Alan
although it's entirely possible that I misunderstood it and used it
in the wrong way. Alan, can you please clear up the confusion?

SFF stands for "Small Form Factor", as in the "SFF Committee Information
Specification for Bus Master Programming Interface for IDE ATA
Controllers Rev 1.0"
from May 16, 1994.
That document is basically a committee rubber-stamp of the earlier Intel
"PCI IDE Controller Specification Revision 1.0" dated 3/4/94.
Ah.. that means we have the whole naming thing wrong. Yewwww....
..
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. :)
