+ help
+ Select this config option if TEE is compiled to include StandAloneMM
+ as a separate secure partition. It has the ability to check and store
+ EFI variables on an RPMB or any other non-volatile medium used by
+ StandAloneMM.
+
+ Enabling this will change the EFI runtime services from the firmware
+ provided functions to TEE calls.
+
+ To compile this driver as a module, choose M here: the module
+ will be called tee_stmm_efi.
