- * Vendor command for ccd factory reset.
- *
- * This vendor command can be used to enable ccd and disable write protect with
- * a factory reset. A factory reset is automatically done during the first
- * factory boot, but this vendor command can be used to do a factory reset at
- * any time. Before calling factory reset, cr50 will make sure it is safe to do
- * so. Cr50 checks batt_is_present to make sure the user has physical access to
- * the device. Cr50 also checks ccd isn't disabled by the FWMP or ccd password.
- *
- * checks:
- * - batt_is_present - Factory reset can only be done if HW write protect is
- *              removed.
- * - FWMP disables ccd -  If FWMP has disabled ccd, then we can't bypass it with
- *              a factory reset.
- * - CCD password is set - If there is a password, someone will have to use that
- *              to open ccd and enable ccd manually. A factory reset cannot be
- *              used to get around the password.
