CFE on bcm12xx, on bcm47xx and bcm63xx are all three slightly different flavors 
which may not behave exactly the same way wrt the load command.

Also, you are on a development board so there are no reasons to restrict CFE 
commands, this is not the case with end-user products like WRT54G and such.
