| H A D | sata_mv.c | 3e4a1391 Fri May 02 01:10:02 CDT 2008 Mark Lord <liml@rtr.ca> sata_mv new mv_qc_defer method
The EDMA engine cannot tolerate a mix of NCQ/non-NCQ commands,
and cannot be used for PIO at all. So we need to prevent libata
from trying to feed us such mixtures.
Introduce mv_qc_defer() for this purpose, and use it for all chip versions.
