11.7 Firmware Update Status Sensor
The BMC FW supports a single Firmware Update Status sensor. This sensor is used to generate SEL events related to update of
embedded firmware on the platform. This includes updates to the BMC, BIOS, and ME FW.
This sensor is an event-only sensor that is not readable. Event generation is only enabled for assertion events.
