Subject: [U-Boot] [PATCH 2/3] SPEAr: Configure FSMC driver for NAND interface
Date: Mon, 27 Feb 2012 15:08:23 +0530	[thread overview]
Message-ID: <1330335504-32226-3-git-send-email-amit.virdi@st.com> (raw)
In-Reply-To: <1330335504-32226-1-git-send-email-amit.virdi@st.com>

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

Since FSMC is a standard IP and it supports different memory interfaces, it
is supported independent of spear platform and spear is configured to use that
driver for interfacing with the NAND device
