Unknown pads on board
According to the datasheet (assuming you're right about the W25Q), these are the Chip Select and data out pins.
So, you're right, on their own, probably not useful. Might still be an important test point where the ability of a controller to initialize itself and read identification from the flash might be tested.
Also, note that this might be something that's &quot;dual use&quot;, if the controller supports it: for example, on boards where the flash is not soldered on (which exists - otherwise the larger unpopulated footprint makes no sense), this might be testing something completely different.
