ARM: sunxi: Add sun4i and cubieboard support
This patch adds support for the Cubieboard based on the Allwinner A10/sun4i SoC. Currently only UART is supported. Other devices will eventually follow. Signed-off-by: Stefan Roese <sr@denx.de> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
