     13  OP-TEE is a piece of software using hardware features to provide a Trusted
     14  Execution Environment. The security can be provided with ARM TrustZone, but
     15  also by virtualization or a separate chip.
     16
     17  We're using "linaro" as the first part of the compatible property for
     18  the reference implementation maintained by Linaro.
