There is a label printed (i.e. ufi001c or uf896 or something else but not getting mainlined now) on the board, different models have different labels(and different board design). And currently I know all ufi001c(even some other models) shares the same device tree, as a downstream device tree has been tested by thousands of people. I'm not familiar with uf896 as it is owned by Nikita Travkin and tested by him. The device sells very well and many people will benefit from mainlining.
