From b687f5d22124ab98693bb44ae4f772934031bba2 Mon Sep 17 00:00:00 2001 From: Venkatesh Yadav Abbarapu Date: Mon, 4 Sep 2023 08:50:34 +0530 Subject: [PATCH] xilinx: versal: Do not setup boot_targets if driver is not enabled SOC can boot in the device which is not accessible from APU and running this is detected as error which ends up in stopping boot process. Boot mode detection and logic around is present to setup priority on boot devices that SOC boot device is likely also used for booting OS. Change logic to detect this case with showing message about it but don't fail in boot process and don't prioritize boot device in this case.
