| # OP-TEE Trusted Execution Environment Configuration |
| config OPTEE |
| bool "OP-TEE" |

| help |
| This implements the OP-TEE Trusted Execution Environment (TEE) |
| driver. OP-TEE is a Trusted OS designed primarily to rely on the |
| ARM TrustZone(R) technology as the underlying hardware isolation |
| mechanism. This driver can request services from OP-TEE, but also |
| handle Remote Procedure Calls (RPC) from OP-TEE needed to |
| execute a service. For more information see: https://www.op-tee.org |
