From d25ea5845360bfcc2771ed876887d5895ebb9d74 Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Wed, 29 Jan 2014 16:20:12 +0000 Subject: [PATCH] ARM: STi: STiH416: Add ethernet support. This patch adds support to STiH416 SOC, which has two ethernet snps,dwmac controllers version 3.710. With this patch B2000 and B2020 boards can boot with ethernet in MII and RGMII modes. Tested on both B2020 and B2000.
