From 6d6564957ced9a29ca62adee68a6e24040dd54be Mon Sep 17 00:00:00 2001 From: Martyn Welch Date: Wed, 10 Jan 2018 20:31:32 +0100 Subject: board: ge: bx50v3: Enable hardware watchdog Enable the hardware watchdog on bx50v3 to cause it to reset in the event the board hangs. Configure GPIO_9 pin as WDOG1_B so that a watchdog timeout results in a full system reset. The watchdog is used and reconfigured by systemd approximately 1.7 seconds into boot. Adding a few seconds for U-Boot and a few more seconds as a safety margin. Note that the PCIe controller is _not_ put back into a safe state prior to board reset. This is a problem if board reset is implemented as CPU reset.
