* to support both, so we only set Dual I/O here to improve our chances
* of compatibility. Since Macronix makes it impossible to search all
* different parts that it recklessly assigned the same IDs to, it's
* hard to know if there may be parts that don't even support Dual I/O
* with these IDs, though (or what we should do if there are).
