* @nr_parts: number of mtd_partitions for static partitoning
* @type: optional flash device type (e.g. m25p80 vs m25p64), for use
* with chips that can't be queried for JEDEC or other IDs
*
* Board init code (in arch/.../mach-xxx/board-yyy.c files) can
* provide information about SPI flash parts (such as DataFlash) to
* help set up the device and its appropriate default partitioning.
*
* Note that for DataFlash, sizes for pages, blocks, and sectors are
* rarely powers of two; and partitions should be sector-aligned.
