No. The old one has more limitations than the new one. The old one in
mainline is half baked since we could never merge the necessary bits
for training. We have been keeping a full version on the OpenBMC tree.

Joel, could we simply drop the old driver in mainline and keep the old
one in the OpenBMC tree until we feel comfortable ? I guess we need
more testing.
