Purpose of P2 jumper on bottom of the board

What's the purpose of the P2 Jumper on the bottom of the board?

Are the pins for the Auxiliary serial audio interface on the CS42448 exposed anywhere?

Oh that jumper is used in programming the boards. One is CDone - you should see it as a high voltage indicating that the FPGA is already programmed. The other is CReset which when driven in the opposite direction for a short period will reset the FPGA.
