This patch add support for the Silica Pengwyn board [1] The board is based on a TI AM3354 CPU [2] All jumpers removed it will boot from the SDcard, the console is on UART1 accessible via the FDTI -> USB. The on board NAND flash is supported and can act as boot medium, depending on jumper settings. USB Host, USB Device and Ethernet are also provided but untested.
