to the sata_sil.c driver too?
Not AFAICT. The 3112 has a Command Protocol Table inside the chip.
Each command reads the ATA command protocol from that table. The table
is programmable (see section 10.3 of [1]), but not on a per-command
basis. The per-command PRD format is pretty much legacy IDE[2], and
nothing like the modern FIS-based controllers.

[2] bmdma2 modifies the PRD format a bit, but it is not relevant to this
