[PATCH 2/2] Switched SAMA5D4EK development board to the newer environment method.

So it looks like the following line in mtdparts-add is causing the
"nand0." issue:
addpart -n /dev/${device} "$parts" || exit
The old environment didn't use the "-n". Removing the "-n" fixes the
issue and gives it the same functionality as the old environment did.
So the question is how should I fix this? I could remove it in the
default environment, but that would require all other boards using the
new environment to update.
Or, I can add my own env/bin/mtdparts-add script for the board and
remove the "-n" from there instead which would leave the other
projects alone. I'm assuming I should use this option as the fix, but
I wanted to confirm that with you.
Thanks,
Doug
