Add universal update_uboot wrapper that helps to update U-Boot image on internal storage.
tftpboot ${loadaddr} ${board_name}/u-boot.img run update_uboot tftpboot ${loadaddr} ${board_name}/SPL run update_spl

Not sure, because: 1. Some platforms use "user" hw partition instead of boot0 for storing SPL/U-boot proper (AFAIK this is actual for i.MX6Q Sabre) IMHO, for this case it's much more convenient to use DFU/UMS/Fastboot (which is not possible for boot0/boot1) for flashing instead of some wrapper like this. 2. I don't have any mx6-based boards other than from Toradex, so at least I won't be able to test it.
If you insist, I can add "update_uboot" to the common include, but to be honest I really doubt that someone will use it :)
