In common/spl/spl_nand.c, why does it only load the environment when
CONFIG_NAND_ENV_DST is defined, yet it never uses the value of
CONFIG_NAND_ENV_DST?  I also don't see any boards definind
CONFIG_NAND_ENV_DST (apparently the only one that ever used it was
smdk6400 which has been removed).

Is there some other way that the environment is supposed to be getting
loaded from NAND (rather than using the default environment) during SPL?
