SPEAr: Configure FSMC driver for NAND interface
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 Signed-off-by: Vipin Kumar <vipin.kumar@st.com> Signed-off-by: Amit Virdi <amit.virdi@st.com> Signed-off-by: Stefan Roese <sr@denx.de> Acked-by: Scott Wood <scottwood@freescale.com>
