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
Mike Lavender2f9f7622006-01-08 13:34:27 -080011 * @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
David Brownell1d6432f2006-01-08 13:34:22 -080013 *
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.
