From 3721998510de23ff77e0f9cbb61c8c5f8c38ddd2 Mon Sep 17 00:00:00 2001 From: Tien Fong Chee Date: Fri, 8 Aug 2025 22:20:42 +0800 Subject: [PATCH] arm: socfpga: Enable ASYNC interrupts in Agilex SPL Asynchronous aborts were previously masked at SPL entry. To ensure early detection of system errors such as ECC faults or bus errors, asynchronous aborts should be explicitly unmasked by clearing the A-bit in the DAIF register during Agilex SPL initialization.
