Bug Description
[Impact]
Using the SBSA watchdog will crash the OS on ThunderX2 systems. This is not an issue in current firmware because the SBSA watchdog is not exposed - but it is likely to be introduced in a future update.
[Test Case]
$ sudo bash
# cat < /dev/watchdog
[Regression Risk]
The fix is restricted the sbsa_gwdt driver, which is only currently available on some arm64 servers.
