At present the only serial driver that is not converted to driver mode is blackfin. As I recently obtained a suitable board from a kind donor I have decided to convert the driver over, as the unpalatable alternative would be to remove blackfin support from U-Boot.
Blackfin's init sequence is someone non-standard. This series adjusts this to fit more with how things are now done, adds device-tree support, a serial driver and enables driver model on bf537-stamp.
A few CONFIG options are dropped in this series also, as these were noticed along the way.
Future work could enhance the serial driver to support v4 hardware and convert all boards to driver model.

Any reviews on this? Will someone pick it up?
