- * Temporary fix for running the TPM selftest and other essential
- * intializations that we forgot to put in the BIOS.
- *
- * This works in a very specific situation: we assume TPM_Startup has been
- * executed, but we don't know if the self test has run.  On a ST TPM version
- * 1.2.7.0, GetCapabilities fails before the self test has run, so we use that
- * to check if we need to run it.
- *
- * This also enables the TPM if it is disabled, and activates it if it is
- * deactivated.
- *
- * Exit status always 0.  Prints "reboot" to request reboot, "fail" for errors,
- * "success" when everything worked.
