Add Redfish messages for watchdog timeout and pre-interrupt + 2. Use dbus properties for power control insted of service files + 3. Use host status to enable/disable watchdog + 4. Set preTimeoutInterruptOccurFlag + 5. Assign watchdog cause for correct reset cause reporting + 6. Add NMI Pre-Interrupt support for IPMI watchdog timer. + +Signed-off-by: James Feist <james.feist@linux.intel.com> +Signed-off-by: Ren Yu <yux.ren@intel.com> +Signed-off-by: Yong Li <yong.b.li@linux.intel.com> +Signed-off-by: Jason M.
