FWIW I've pushed out a QEMU tree with the MPAM patches posted previously
and an additional one enabling DSPRI on all the caches +
introspection and some additional sanity checks to pick up on the width
of DSPRI bug Amit fixed.
I used that to test this series and it seems fine subject to the TODO
on the final patch.
Note that's a simple model and doesn't actually do anything but is easy
to modify to poke corner cases / features you don't hardware for etc.

(there is an outstanding build issue for arm32, so don't build that :)
