BIOS FWH State Change Sensors
The IPMC implements two BIOS firmware hub sensors (event/reading type 03h=Digital
Discreet, sensor type 0xC0=EOM, sensor numbers 54h and 55h).
First sensor (0x54: "BIOS FWH0 Flash") indicates state of first firmware hub selection.
Second sensor (0x55: "BIOS FWH1 Flash") indicates state of second firmware hub
selection.

Reset Sensor
Every reset generated by IPMC is also logged to SEL. After reset signal assertion the
IPMC logs SEL event from event-only sensor "Forced Reset". Only one offset is logged:
offset 01 = "State Asserted".
Event data 2 contains Reset Type:
Event Data 3 contains reset cause, as defined in following
