SVN rev 197402 on 2009-09-22 11:47:21Z by marius
- Add missing bus_dmamap_sync(9) calls for the work DMA map. Previously
the work area was totally unsynchronized which means this driver only
had a chance of working on x86 when no bounce buffers were involved,
which isn't that likely given that support for 64-bit DMA is currently
broken throughout ata(4).
- Add necessary little-endian conversion of accesses to the work area,
making this driver work on big-endian hosts. While at it, use the
alignment-agnostic byte order encoders in order to be on the safe side.
- Clear the reserved member of the SG list entries in order to be on the
safe side. [1]
