Subject: [U-Boot] [PATCH 05/25] SPEAr: Add macb driver support for spear310 and spear320
Date: Wed, 7 Mar 2012 17:33:54 +0530	[thread overview]
Message-ID: <1331121854-20494-6-git-send-email-amit.virdi@st.com> (raw)
In-Reply-To: <1331121854-20494-1-git-send-email-amit.virdi@st.com>

From: Vipin KUMAR <vipin.kumar@st.com>

SPEAr310 and SPEAr320 SoCs have an extra ethernet controller. The
driver for this device is already supported by u-boot, so configuring
board configuration file and defining base addresses etc to make use
of the common driver
