Yes, we're very excited about this ;-)

Would you mind putting a patch together (for after v3.10 drops) to do
this?  If you applied Sebastian's series on top of mvebu/pcie_kirkwood,
that should get you almost there.  The last half of his series is going
in after v3.10...

You may want to try merging in mvebu/boards and mvebu/soc.  Those have
the changes to use dt for the restart and power-off drivers.  That'll
allow us to empty out a few more board files.  mvebu/dt also has a patch
from Valentin allowing us to remove the keymile board as well.

thx,

Jason.
