mtd: NOR flash driver for OMAP-L137/AM17x
OMAP-L137/AM17x has limited number of dedicated EMIFA address pins, enough to interface directly to an SDRAM. If a device such as an asynchronous flash needs to be attached to the EMIFA, then either GPIO pins or a chip select may be used to control the flash device's upper address lines. This patch adds support for the NOR flash on the OMAP-L137/ AM17x user interface daughter board using the latch-addr-flash MTD mapping driver which allows flashes to be partially physically addressed. The upper address lines are set by a board specific code which is a separate patch.
