Why is this in here? Why not put it in the generic ops file?
This function is a good interface, we will use it many times in the
future.
generic ops file is only used to some operation can be used for
different chip,
some special chip may replace generic ops by provide their own ops.
So generic ops file is just use to abstract the same code, not for
good interface.
