Try enabling CONFIG_NAND_ENV_DST to have the environment be loaded by the
SPL along with the main U-Boot image.  You didn't say what board/chip
you're using, so if you're using something other than the common
nand_boot.c you may need to add support for this (it's just a couple
lines), and silence any output from the SPL itself.
