From f055f1f682b84b3b785813f5c11efacab6001253 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Mon, 19 Nov 2012 12:09:42 +0100 Subject: [PATCH] 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.
