If I remember correctly, the main issue is that the ci_udc driver is 
missing DM support. See here: [1].

I have pulled some patches/hacks into our tree to make SDP work, at 
least without DM [2].

If someone could come up with a proper solution for upstream that would 
be great and I would be happy to review/test.
