I've updated the patch at
slighlty based on feedback I got during review. Could
you please give the new version (which has an MD5 hash
of a56305fef5edb1d1510373b7e063aaab) a sanity check?
Some basic transfer should be sufficient to verify
it still works. If no new problem arises I'll commit
the patch to head, stable/8 and stable/7.

AFAICT the "old" ata-siliconimage(4) suffers from the
same bugs as ata-marvell(4) does, i.e. isn't endian
clean and misses DMA synchronisation besides 64-bit
DMA being broken, but isn't as straight forward to
fix as ata-marvell(4) is. The new siis(4) doesn't
have these bugs though, so I'd expect it to work fine.
Have you talked to mav at regarding siis(4)?
