| 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. |
