[PATCH v2 3/3] ARM: mvebu: Add initial support for Turris Omnia

Uwe Kleine-König u.kleine-koenig at pengutronix.de
Thu Jun 15 00:59:16 PDT 2017 

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 at pengutronix.de>

Changes since (implicit) v1:
 - fix copyright stuff
 - drop some debug remains
 - fix kwboot.cfg
