+ * value of TRUE. The specs say nothing about STCLEAR flags, so they should be
+ * left alone. This test checks that both flags may be reset without a reboot,
+ * resulting in a fully enabled and activated TPM. (We know that because
+ * ForceClear requires that the TPM be enabled and activated to run.)
