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.
