Curious, but when is this option actually useful?

Good point.  I will remove that bit, it was used as an aid in debugging
while bringing up the patch set.

this is handy in debugging new platforms.
this boot argument option forces to boot as single node dummy system
adding all resources to node0.

This is used to disable numa in a numa enabled kernel esp. for
debugging/enabling/booting single node systems. Same kernel parameter
as for x86 and other archs. Should not being removed.
