This patch adds the NAND SPL framework needed to boot i.MX31 boards from NAND. It has been tested on a i.MX31 PDK board with large page NAND. Small page NANDs should work as well, but this has not been tested. Note: The i.MX31 NFC uses a non-standard layout for large page NANDs, whether this is compatible with a particular setup depends on how the NAND device is programmed by the flash programmer (e.g. JTAG debugger). The patch is based on the work by Maxim Artamonov.

rename to serial_mxc UART hardware on i.MX27 is the same as on the i.MX31 so we just need to provide the driver with correct address of the registers.

Unused functions like udelay_masked() have been removed as no driver uses them, even the ones that are not currently active for this board. mtu.h is copied literally from the kernel sources.
