+	  This implements a generic interface towards a Trusted Execution
+	  Environment (TEE). A TEE is a trusted OS running in some secure
+	  environment, for example, TrustZone on ARM cpus, or a separate
+	  secure co-processor etc. See also:

+	help
+	  This emulates a generic TEE needed for testing including the AVB
+	  TA. The emulation provides all callbacks of a regular TEE and
+	  supports session and shared memory management. The AVB TA is
+	  emulated with rollback indexes and device lock-state, the state
+	  of the TA is only kept in RAM and will be reset on each boot.
+	  The emulation only supports one open session at a time.
+	  Interaction from the U-Boot command line in possible via the
+	  "avb" commands.
