Was thinking about this some more and realized I don't like  
fdt_memory() getting called via bootm w/o the board code have control.

I think Kim suggest we have a CONFIG_OF_MEMORY_FIXUP that this call is  
wrapped around.  But leave fdt_memory() available.  I want it such  
that the board code/config is in control of what fixups gets called  
for it.

There are cases in which we don't want fdt_memory() called as it stands.
