Subject: [PATCH 02/12] efi: add proper reset hook
Date: Mon, 8 Dec 2014 14:42:29 +0100 [thread overview]
Message-ID: <1418046159-29843-2-git-send-email-l.stach@pengutronix.de> (raw)
In-Reply-To: <1418046159-29843-1-git-send-email-l.stach@pengutronix.de>
This allows to actually reset the system from barebox
instead of dropping back into the EFI firmware.
