From f833d6a4ce5ba890eadcae1846c59812478e909c Mon Sep 17 00:00:00 2001 From: Chin Liang See <chin.liang.see@intel.com> Date: Wed, 5 Aug 2020 18:34:33 +0800 Subject: [PATCH] configs: socfpga: soc64: Avoid SPL enter infinite loop during exception In current implementation, any exception would trigger a CPU reset. But a bad written SPL would cause infinite loop where the system will reload the same SPL instead of loading factory safe image. Hence this patch is to ensure any exception will cause a hang. At this moment, watchdog shall be triggered and Remote System Update mechanism shall load the next production image or factory safe image.
