The patch adds the possibility to update the QONG
FPGA (a Lattice XP2-5E) with u-boot using some GPIOs
to drive the JTAG interface.

The NAND device is connected to the FPGA of the QONG board
and not to the NFC controller. For this reason, the FPGA must
be set and initialized before accessing to the NAND itself.
