^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  2) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  3) The SBSA Generic Watchdog Timer is used to force a reset of the system
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  4) after two stages of timeout have elapsed.  A detailed definition of the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) watchdog timer can be found in the ARM document: ARM-DEN-0029 - Server
