We should have a common limit rather than a configurable option; there's
no point building a compatibility nightmare for ourselves when the only
thing we lose is a few entries in the fixmap.
I'm happy to bump the max size for the DTB, but I'd like to see a
reasonable example of a DTB approaching or exceeding that first.
Mark.
