Yes, I have considered abstracting this but I've decided that there is
sufficient number of differences to justify adding new code.

It is not only that, HPM clock sourcing checking would also need to be
abstracted somehow.  Anyway there is not a lot of new code and it so
much easier to follow by not being shared that I would prefer to keep
it that way.
