Add board support for hawkboard
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.
* hawkboard_uart_config - This is same as the first image, but with
the TEXT_BASE as expected by the RBL(0xc1080000). Create the AIS
