Looking at Linux kernel, U-Boot, Qemu, EDK II, that's right :) I guess that applies to the so-called non-secure world. > > You should participate in the System DT discussions in Linaro where > how to represent different CPUs and CPU execution environments (like > secure world) is being worked on. Fair, I'll get information there. Thank you for your prompt feedback. In the same scope, I am to post a change in the Linux DTS files. A change to define a new attribute mostly of interest for the secure world description. I will still post it to the LKML to get feedback about it.
