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> --- This patch has been tested on DA850/OMAP-L138 EVM. This patch depends on the following patches which I have submitted to davinci git: [PATCH] davinci: Add MMC/SD support for da850/omap-l138 [PATCH] davinci: Configure MDIO pins for EMAC [PATCH] davinci: Add NAND flash support for DA850/OMAP-L138 arch/arm/mach-davinci/board-da850-evm.c | 62 ++++++++++++++++++++++++++++ arch/arm/mach-davinci/da850.c | 51 +++++++++++++++++++++++ arch/arm/mach-davinci/include/mach/da8xx.h | 2 + arch/arm/mach-davinci/include/mach/mux.h | 35 ++++++++++++++++ 4 files changed, 150 insertions(+), 0 deletions(-)
