I don't think it matters if the HBA is on the motherboard or not. Since
SAS can support attaching SATA and SATA/ATAPI devices via STP, we could
certainly end up with HBAs that support both SAS and SATA devices. Where
would such a driver exist? If libata moves into the ata directory, it seems
like it would be more difficult for a single LLD to support both SAS and SATA.
