config LIBTEEC
	bool "TEE client library (libteec)"
	default n
	---help---
	        Enable libteec from https://github.com/OP-TEE/optee_client. This
	        is OP-TEE project's implementation of GlobalPlatform's TEE client
	        API specification v1.0 (GPD_SPE_007):
	         https://globalplatform.org/specs-library/?filter-committee=tee
	        The TEE Client API describes and defines how a client running in
	        a rich operating environment (REE, in this case NuttX) should
	        communicate with the Trusted Execution Environment (TEE) and its
	        Trusted Applications (TAs). The library provides a
	        well-established and easy-to-use interface abstracting away much
	        of the details of the underlying subsystems. For more information
	        please refer to:
	        https://optee.readthedocs.io/en/latest/architecture/globalplatform_api.html#tee-client-api
