Is it possible to connect USB HS PHY ULPI interface (e.g. Microchip USB3300) to SmartFusion2 KiskStart Board?

The KickStart board does not use the SmartFusion2 USB interface and does not have an ULPI PHY. One can connect a ULPI PHY to a SmartFusion2 device as per some of the Microsemi board reference designs (the M2S090 Eval Board uses the USB3320), but on this board the USB interface is taken to a quad USB to serial converter, so the SoC only sees a serial port and a JTAG interface. If you look at the KickStart board schematic you will see that the multi-purpose I/O pins that can be used for a USB interface are taken to some of the PMOD connector pins, where they can be accessed.
