    The patch adds basic board support for TI's OMAP-L138 based
    Hawkboard. This board is pretty similar to the da850 EVM. Support for
    nand and network access is added in this version.
    
    The following bootup procedure is used.
    
    At reset, the Rom Boot Loader(RBL), initialises the ddr and the nand
    controllers and copies the second stage bootloader(nand_spl) to
    RAM. The secondary bootloader then copies u-boot from a predefined
    location in the nand flash to the RAM, and passes control to the
    u-boot image.
    
    Three config options are supported
    * hawkboard_config - Used to create the u-boot.bin. Tftp the
     u-boot.bin image to the RAM from u-boot, and flash to the nand flash
     at address 0xe0000.
    
    * hawkboard_nand_config - Used to generate the secondary
     bootloader(nand_spl) image. This creates an elf file u-boot-spl
     under nand_spl/. Create an AIS signed image using this file, and
     flash it to the nand flash at address 0x20000. The ais file should
     fit in one block.
