+Description:
+ Contains the First Failure Data Capture from the SBEFIFO
+ hardware, if there is any from a previous transfer. Otherwise,
+ the file is empty. The data is cleared when it's been
+ completely read by a user. As the name suggests, only the data
+ from the first error is saved, until it's cleared upon read. The OCC hwmon driver, running on
+ a Baseboard Management Controller (BMC), communicates with
+ POWER9 and up processors over the Self-Boot Engine (SBE) FIFO.
+ In many error conditions, the SBEFIFO will return error data
+ indicating the type of error and system state, etc.
