ARM: gk802: Add support for Zealz GK802
Add support for the GK802 'QUAD CORE Mini PC', which seems to be loosely based on the Freescale i.MX6Q HDMI dongle reference design. It is supposedly identical to the Hiapad Hi802. Signed-off-by: Philipp Zabel <philipp.zabel@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
