HW validation would like to use parts of the real Linux driver to
exercise the HW, instead of writing their own driver.

This is a very custom environment (not a full OS) and the code needs to
be preprocessed for it. The hwapi tag tells our preprocessor which
functions must be left in.

We thought that this would be less intrusive than moving the code to a
separate file, which would force some unneeded changes to the code.

Thanks,
