The driver is based on Synopsys driver 2.60a.

We started to prepare open source submission based on our internal
version. We sync this version to linux-2.6-denx repository from time to
time. I'll sync the driver to the latest linux-2.6-denx as Wolfgang
pointed out, and re-submit patch to open source.

We modified the driver mostly to follow Linux kernel coding style.  
Both USB host and device modes are tested.
