Well, I agree, but the effect of this patch is that it is possible to have 
first bank (or rather section) up to 512MiB, in case of CONFIG_SPARSEMEM.

Still, we could go the other way and just define more smaller sections 
instead and simply drop this patch. (Assuming that the correspondence of 
sections and memory banks is irrelevant.)
