Please note that the Synopsys USB driver in our  tree  has  not  been
maintained  for  a long time. Over time, it detoriated. Only recently
we have put some more efforts into it to at least make it work again.
It still is in a pretty poor state, which is the main reason we never
attempted to push this upstream.  [In  my  opinion  it  needs  to  be
rewritten from scratch.]

For the relevant changes please see for example

Please use a more recent kernel version - either use top of tree from
the master branch of our repository, or a recent version from our
2.6.30.y or 2.6.31.y stable branches, i. e at least DENX-v2.6.30.3 or
DENX-v2.6.31.4


Best regards,
