I just did this part and it seems to have semi-bricked the board. It 
gets as far as:
===
U-Boot 2013.04 (Jun 02 2015 - 10:54:10)ooREV: 1.15.01-F05 ( uart0 )
===

and it just stops.

That seems a bit odd from just changing one variable and adding another, 
I didn't think those were supposed to be read until after the boot 
interruption prompt.

On to unbricking procedure I go...
