Well, not exactly.  It's about allowing more than one location to be
enabled.  For example, raw eMMC when that makes sense or FAT file when
that makes sense.  If Lokesh ack's the change (or passes MAINTAINER over
to someone else who acks), OK, we'll do this.  But there's intentional
reasons we've put it in a file in FAT before, even on this platform.
But maybe use cases have changed, and that's fine.
