	   Freescale's IMX series include an integrated full speed

	   USB 1.1 device controller.  The controller in the IMX series

	   is register-compatible.

	   It has Six fixed-function endpoints, as well as endpoint

	   zero (for control transfers).

	   Say "y" to link the driver statically, or "m" to build a

	   dynamically linked module called "imx_udc" and force all

	   gadget drivers to also be dynamically linked.
