Subject: [Qemu-devel] [PATCH] zynq: Request qemu reset when PSS_RESET_CTRL triggered.
Date: Mon,  3 Feb 2014 15:33:09 +1100	[thread overview]
Message-ID: <1391401989-52312-1-git-send-email-chrisj@rtems.org> (raw)

If 1 is written to the SLCR's PSS_RESET_CTRL register request a qemu
reset.

The RTEMS BSPs use this bit and if -no-reboot is used qemu exits cleanly.
