   7 * struct flash_platform_data: board-specific flash data
   8 * @name: optional flash device name (eg, as used with mtdparts=)
   9 * @parts: optional array of mtd_partitions for static partitioning
  10 * @nr_parts: number of mtd_partitions for static partitoning
  11 * @type: optional flash device type (e.g. m25p80 vs m25p64), for use
  12 *      with chips that can't be queried for JEDEC or other IDs
  13 *
  14 * Board init code (in arch/.../mach-xxx/board-yyy.c files) can
  15 * provide information about SPI flash parts (such as DataFlash) to
  16 * help set up the device and its appropriate default partitioning.
  17 *
  18 * Note that for DataFlash, sizes for pages, blocks, and sectors are
  19 * rarely powers of two; and partitions should be sector-aligned.
