Subject: [PATCH] commands: reset: add shutdown_barebox() before reset_cpu()
Date: Tue, 29 Jan 2013 15:03:05 +0400	[thread overview]
Message-ID: <1359457385-24232-1-git-send-email-antonynpavlov@gmail.com> (raw)

Some of controlled by barebox peripheral devices may be
not affected by CPU reset, so we need call shutdown_barebox()
to stop them.
