    3 OP-TEE is a piece of software using hardware features to provide a Trusted
    4 Execution Environment. The security can be provided with ARM TrustZone, but
    5 also by virtualization or a separate chip.
    6 
    7 We're using "linaro" as the first part of the compatible property for
    8 the reference implementation maintained by Linaro.

   10 * OP-TEE based on ARM TrustZone required properties:
   11 
   12 - compatible     : should contain "linaro,optee-tz"

   14 - method         : The method of calling the OP-TEE Trusted OS. Permitted
   15                    values are:

   17                    "smc" : SMC #0, with the register assignments specified
