Are you planning to improve ci13xxx_udc ? AFAIK ci13xxx_udc lacks some features that are implemented by other drivers. For example the fsl one handle endianness. Also it could be interesting to benchmark all the existing drivers to see which one is better. In the old days ci13xxx_udc was very slow. Also don't forget that there are different version of the core. For example ci13xxx_udc doesn't support older core that doesn't have USBADRA.
