I'll make sure to label it.

I don't think I've seen a modern platform where this isn't 2MB, so I
think it's safe to add it to the platform. But a label sounds good, if
someone out there has a custom modem firmware with some odd changes in
this area.
I'll label it, to make it possible to move, resize or reclaim in boards.
