Use the first compatible string as board name in userspace. Add the new board name as well as the former used board name to the image metadata to keep compatibilty with already deployed installations. Don't add the former used boardname for boards which exists only in master or evaluation boards. Signed-off-by: Mathias Kresin <dev@kresin.me>
