+         ARM SBSA Generic Watchdog has two stage timeouts:
+         the first signal (WS0) is for alerting the system by interrupt,
+         the second one (WS1) is a real hardware reset.
+         More details: ARM DEN0029B - Server Base System Architecture (SBSA)
+
+         This driver can operate ARM SBSA Generic Watchdog as a single stage
+         or a two stages watchdog, it depends on the module parameter "action".
+
+         Note: the maximum timeout in the two stages mode is half of that in
+         the single stage mode.
+
+         To compile this driver as module, choose M here: The module
+         will be called sbsa_gwdt.
