Well, this is exactly the point here: to explain the concept. I don't think focusing on a single implementation helps in that. It's clear that TrustZone and SMI have pretty much the same side-effects, so I think it's better to present the general concept as privileged execution environments instead of only naming one example. -- Paul Kocialkowski, developer of free digital technology and hardware support Website: https://www.paulk.fr/ Coding blog: https://code.paulk.fr/ Git repositories: https://git.paulk.fr/ https://git.code.paulk.fr/
