2nd mention of TPO and MMP in a month. May want to get these memory map locations documented.

Honestly, its hard to commit much time to it. We about 1 request every 5 years. Most people use PAC Control and it just works there with no faffing about. That said, I am always happy to run it up the flag pole and see what the team thinks.
