Subject: [PATCH 3/3] ARM: mvebu: Add initial support for Turris Omnia
Date: Wed, 14 Jun 2017 23:50:10 +0200	[thread overview]
Message-ID: <20170614215010.11886-3-u.kleine-koenig@pengutronix.de> (raw)
In-Reply-To: <20170614215010.11886-1-u.kleine-koenig@pengutronix.de>

Up to now only 2nd stage booting is tested and boots up to a prompt.
i2c and spi are working, ethernet, usb and sata don't.

Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
