+ * |
+ * ForceClear sets the permanent disable and deactivated flags to their default |
+ * 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.) |
