    The platform may be comprised of multiple hardwaare modules with
    functionality on daughtercards which can be probed at runtime. You may
    also find someone constructing a PCI card or something with a slimbus
    controller on it at some point.

    It seems a bit extreme to prevent anyone implementing a subsystem for
    their platform until they've converted it into device tree. Though with
    slimbus it should be at least somewhat probeable IIRC?
