Sorry for being silent during the last days. I was preparing the
porting of our open-source Trustzone monitor (SafeG) to QEMU. The good
news is that it is working and it can be downloaded here (it runs an
RTOS called FMP on the trusted world and Linux on the non-trusted
world). Note: I also have a smaller bare-metal test, which can be
useful for small tests.

I agree with you Johannes. Let's start simple. I will try to find time
this month to do something about it.

Best regards,
Daniel
