+Subject: [PATCH] Interface for ibm,physical-attestation rtas call
+
+The physical attestation interfaces are provided to allow a
+trusted 3rd party client to retrieve information about the
+trusted boot state of the target PowerVM system. This makes
+use of the systems physical TPM(s). These TPM(s) are used
+by system firmware to extend measurements during the
+boot process.
