- Generic Hardware Error Source provides a way to report
- platform hardware errors (such as that from chipset). It
- works in so called "Firmware First" mode, that is, hardware
- errors are reported to firmware firstly, then reported to
- Linux by firmware. This way, some non-standard hardware
- error registers or non-standard hardware link can be checked
- by firmware to produce more valuable hardware error
- information for Linux.

- This option should be enabled if the system supports
- firmware first handling of SEA (Synchronous External Abort).
- SEA happens with certain faults of data abort or instruction
- abort synchronous exceptions on ARMv8 systems. If a system
- supports firmware first handling of SEA, the platform analyzes
- and handles hardware error notifications from SEA, and it may then
- form a HW error record for the OS to parse and handle. This
- option allows the OS to look for such hardware error record, and
- take appropriate action.

- if you want to debugging and testing the ERST kernel support
- and firmware implementation.
