Sounds reasonable, although I'd prefer the TZ memory to be discrete, outside of the SoC. We don't want TZ to evolve into IntelME, do we? ;)https://twitter.com/AndreaBarisani/status/790497935918235648 …
TZ exists solely to allow arbitrary user code to run partitioned in Secure domain, it is an anti-harcoded-ROM security feature

with user != userspace, of course vendors can lock and secure boot TZ if they want, but those are integrators and not SoC makers
