The full NAND code only works after relocation. So you cannot read out the NAND environment, in the normal way, before serial init -- you get the default environment instead.
If you are booting from NAND, I suggest using CONFIG_NAND_ENV_DST to have the NAND SPL load the environment at the same time as it loads U-Boot. If you're using some preloader other than U-Boot's NAND SPL, you'll need to see if it supports something similar.
Hello Scott
Is this feature available/tested on any FSL platform. The code you pointed to does not seem to be used by FSL platforms.
It would be good idea to pull this in for P1/P2 RDB nand boot loader.
It is currently only supported in nand_boot.c, but it should be trivial to add it to nand_boot_fsl_elbc.c. Just copy the extra nand_boot() invocations.
