omap3: Add support for flash on 3430SDP board
This patch adds support for flashes on 3430SDP boards. All three
NAND, NOR and OneNAND are supported. I have tested it on
3430SDP (ES2 and ES3.1).
This patch can be treated as an example to "how to utilize":
'gpmc-nand.c' and 'board-sdp-flash.c'.
Similar patches can be created for 2430sdp and 3630sdp or any other
similar board.
