You must enable (define) CONFIG_CMDLINE_TAG. OTOH, defining CONFIG_BOOTARGS
is optional. If you do define CONFIG_BOOTARGS, it sets the default env
bootargs if same is not present in saved flash env already. Else if you
undef CONFIG_BOOTARGS, then you can always do `setenv bootargs ...` to
set it and `saveenv` to save it.

HTH!

P.S. Make sure you've specified the correct BOOT_PARAMS phys addr for your
machine, i.e. make sure your machine boot_params agree between u-boot and
linux:

	grep -i boot_params ../u-boot/board/*/*.c ../linux/arch/arm/mach-*/*.c
