From 6521f6a195c70e16cab375ca1c4d23b6fd3d76b4 Mon Sep 17 00:00:00 2001 From: Alexander Sverdlin Date: Wed, 21 Feb 2024 16:45:51 +0100 Subject: ARM: AM33xx: PRM: Implement REBOOT_COLD Historically AM33xx performed warm software reset even though requested (and default) was REBOOT_COLD. Reflect the de-facto default mode in /sys/kernel/reboot/mode correctly and implement the real REBOOT_COLD (if configured explicitly).
