[PATCH] spi: M25 series SPI flash
This was originally a driver for the ST M25P80 SPI flash. It's been updated slightly to handle other M25P series chips. For many of these chips, the specific type could be probed, but for now this just requires static setup with flash_platform_data that lists the chip type (size, format) and any default partitioning to use.
