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