In-Reply-To: <20200506191246.237790-1-ilias.apalodimas@linaro.org>

If OP-TEE is compiled with an EDK2 application running in secure world
it can process and store UEFI variables in an RPMB.
Add documentation for the config options enabling this

+Using OP-TEE for EFI variables
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If an RPMB and it's drivers is available in U-Boot, OP-TEE can be used for
+variable services.
+Enabling CONFIG_EFI_MM_COMM_TEE=y will dispatch the variables services to
+OP-TEE. OP-TEE needs to be compiled with a secure application (coming from EDK2)
+which will process variables in the Secure World and store them in the RPMB
+using the OP-TEE supplicant.

 Executing the boot manager
