If the Security extension is present on a cpu, then there should be at least a trivial monitor code and services. And Secure world may restrict Non-secure world significantly in what that may do with the hardware. Some configuration things are only accessible from the Secure state. If TZ isn't used at all, how those things are configured? And in general, maybe you know this, I'm on the beginning of learning arm internals, and I can not get it, - is it possible for an arbitrary software writer to implement and put it into the SoC his own Secure World software stack with the Monitor includingly? I even asked this on the arm community and the answers were not quite giving a feel of clear understanding. -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
