omap3: SDP: Introducing 'board-sdp-flash.c' for flash init This patch adds 'board-sdp-flash.c', which could be utilized by boards similar to 3430SDP. (For ex: 2430sdp, 36030sdp). This file does initialization for all three flash devices present in SDP boards (NOR, NAND, OneNAND), by finding there 'cs' number dynamically using switch setting information (S8: 1-4). This also expects partition information from core board files (for ex: board-3430sdp.c). Which allows to choose different default partitions for different boards. A new structure is created for this purpose: 'flash_partitions' in 'mach/board-sdp.h'. This has two members: 1. struct mtd_partition *parts 2. int nr_parts A board file is expected to fill this structure and pass it to 'sdp-flsash-init'. Partition information should be passed in structure array of 'flash_partitions'. Partition information should be passed in below sequence in array: NOR OneNAND NAND Signed-off-by: Vimal Singh <vimalsingh@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
