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 Signed bin, as use the normal UART boot procedure to boot the image.

I believe Wolfgang just sent a patch where he got rid of these SYS_TEXT_BASE and then replaced them with CONFIG_SYS_TEXT_BASE in the config.h files.
I don't think that patch is in Wolfgang's next branch though
Please keep this in mind and resubmit after rebasing with u-boot-ti/next
