As I said in another email:
"The main purpose of CONFIG_ONENAND_IPL and NAND_SPL in start.S is to
change the behaviour a bit, not so much to save some space."
Given that those CONFIG_s are used in other places as well to indicate
the type of boot I don't think it's good to create a new CONFIG_ that
one has to specify in addition to one of the above.
