# Extra variables:
# script_dev_usb 'usb X.Y' default usb instance:partition to boot from.
# script_dev_mmc 'mmc X.Y' default mmc instance:partition to boot from.
# script_dev $script_usb|mmc_dev depending on media where boot script was found.
# script_fsload 'fatload' or 'ext2load' depending on which was used to load boot script.
# dram_base DDR start address
# dram_size DDR size (in bytes)
# load_addr default load address (DDR start)
# board board id ("b2120", "b2260", ...)
