sunxi: Add sun5i support
Add support for the Allwinner A13 and A10s SoCs also know as the Allwinner sun5i family, and the A13-OLinuXinoM A13 based and r7-tv-dongle A10s based boards. The only differences compared to the already supported sun4i and sun7i families are all in the DRAM controller initialization: -Different hcpr values -Different MBUS settings -Some other small initialization changes Signed-off-by: Henrik Nordstrom <henrik@henriknordstrom.net> Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Oliver Schinagl <oliver@schinagl.nl> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
