OMG yes that makes perfect sense. I questioned this in the past and was
pointed to the same manual page.

What is fun is that the code was written by ARM.

Let's merge this and I'll test it on the PB11MPCore, I think Mem2Mem
with the DMA engine compile-in tests may work on a few other boards as
well so maybe Russell can test it too.
