TrustZone is not DRM nor a management engine like Intel's ME. It is just a reference design in order to implement some sort of sandbox and security zone in the SoC.
ARM doesn't mandate how TrustZone is used, it just provides the technology. If SoC designers use it to force DRM into their products, it's not really ARM's fault.
Also, just to make it clear, it is not ARM's fault if ARM based SoCs lack proper documentation.
- subway 9y agoIt's at least partially ARM's fault, as ARM doesn't publish documentation for their cores. SoC vendors are just as bad, if not worse, but ARM doesn't get off scott-free.
