OK, so those defines are used. There's a surprising amount of unused
defines that end up in include/configs/ so I want to be sure when I see
a new one pop up.

As a tangent, are these actually board specific? My first glance is that
we're just saying where memory could be, rather than is all of memory
and so it should just be a static "starts here, takes up the remaining
2GB of address space".
