I have no idea what your code does, but using the timer that is
integrated into the core (just like on any other A9 implementation)
feels like the right thing to do, unless the HW is too broken to use
TWD.

Another timer is a nice thing to have (it probably comes in handy for
suspend/resume, and it may have a much better resolution), but this
seems like icing on the cake at this point. Let's see the cake first.

Thanks,
