From 4be87603b6dc9e49c2e07151bb51180dc0b6964a Mon Sep 17 00:00:00 2001 From: Angelo Dureghello <angelo.dureghello@timesys.com> Date: Fri, 2 Oct 2020 16:05:45 +0200 Subject: [PATCH] serial: mcf: add sysrq capability After some unsuccessful attempts to use sysrq over console, figured out that port->has_sysrq should likely be enabled, as per other architectures, this when CONFIG_SERIAL_MCF_CONSOLE is also enabled. Tested some magic sysrq commands (h, p, t, b), they works now properly. Commands works inside 5 secs after BREAK is sent, as expected.
