As in reserved-memory/reserved-memory.txt? Might refer to that doc here.
Or is this some other kind of reserved memory?

If the former, it's normally called just "memory-region", although
that does seem somewhat non-descriptive...

Do you really need both of these? It seems like your code uses one or
the other, not both. In which case, this is not a very good description,
because it sounds like they would go together.

Also, if you're not using standard/generic properties (e.g., the
aforementioned "memory-region" binding), you typically should use a
vendor prefix, like "qcom,msa-size".

Devicetree folks, any comments? I would like to apply this via my
ath.git tree but need help with the review.
