It merged to mainline yesterday; should verify on DM6446 EVM.

The funky bits are fortunately limited to the 4-bit ECC support,
which are natural to review/evaluate as deltas on top of that core.
It was easy to tell they would bring out some confusion, which is
a good sign of something that's worth reviewing separately.

And, given the patches I referenced previously ... even those
should only be an issue for large page chips.  (And no DaVinci
board that uses large page chips has hit mainline yet.  Lots of
stuff in the queue for, one hopes, 2.6.31 though.)
