davinci: Add NOR flash support for da850/omap-l138
This patch adds platform data for the 8MB NOR flash found on da850/omap-l138 EVM. Both NOR and NAND can co-exist on da850/omap-l138 as they are using different chip selects. Signed-off-by: Sudhakar Rajashekhara <sudhakar.raj@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
