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.
