In OP-TEE we can run EDK2's StandAloneMM on a secure partition. StandAloneMM is responsible for the UEFI variable support. In combination with OP-TEE and it's U-Boot supplicant, variables are authenticated/validated in secure world and stored on an RPMB partition. So let's add a new config option in U-Boot implementing the necessary calls to OP-TEE for the variable management.
