[PATCH] msf2-soc, stellaris: Don't wire up SYSRESETREQ


From: Peter Maydell
Subject: [PATCH] msf2-soc, stellaris: Don't wire up SYSRESETREQ
Date: Mon, 12 Oct 2020 16:33:47 +0100

The MSF2 SoC model and the Stellaris board code both wire
SYSRESETREQ up to a function that just invokes
    qemu_system_reset_request(SHUTDOWN_CAUSE_GUEST_RESET);
This is now the default action that the NVIC does if the line is
not connected, so we can delete the handling code.
