When I saw the patch allowing to generate both in-tree and out of tree DTS, I also thought "but why do we keep those booleans". Next time I should not only "think" but also write it in an e-mail as a reply to the patch :-) Thomas

Just use whatever the user specified in the list. An empty list means no DTS was specified. No need to add legacy option, as the behaviour does not change. Signed-off-by: "Yann E.
