ARM: omap3_logic: Add NOR Flash Support for SOM-LV
The DM37 and OMAP35 SOM-LV SOM-LV products both support a NOR flash part connected to CS2 in addition to the NAND part on CS0. This patch setups the GPMC timings for the MT28 NOR Flash and enables the CFI-Flash driver now that the CFI stuff is in Kconfig Signed-off-by: Adam Ford <aford173@gmail.com>
