System Event Log (SEL)

A 64 kB System Event Log (SEL) is implemented in the BMC. It stores all events that
are either generated by the BMC or that are passed to it from the system interface.
The events are physically stored in the external attached SPI flash.
All received events are passed to the default event receiver (which typically is the
CMM in PICMG2.9 environments if one is present), regardless of being stored in the
SEL. This means that local events will show up in the local BMC's SEL as well as in
the CMMs shelf wide SEL, unless there is no filter enabled on the CMM side.
The size of 64 kB is sufficient to hold exactly 4096 entries of 16 bytes each.
Once the SEL is full, it will not store new entries so that existing data is not overwrit-
ten. The SBC or System managers can query the SEL usage at any time and it is
their responsibility to issue a "SEL Clear" from time to time to avoid local SEL over-
flow.

Sensors

All important voltages and temperatures are connected to the BMC management
system in different ways.
Moreover, the BMC also registers some logical sensors listed below:
 BMC Watchdog sensor
 FW Progress sensor
 Version change sensor
 Advantech OEM Sensor: Integrity Sensor
