I disagree for the reason that once you discover more apps running on the secure side, you want to add more entries and update DT on the platform every time you discover some new firmware entity and you wish to interact with it from the non-secure side. As along as get this application ID can handle any random name, I prefer to use that as the discover mechanism and not have this DT. -- Regards, Sudeep
