This is a conversion of the AT91rm9200 DataFlash MTD driver to use the lightweight SPI framework, and no longer be AT91-specific. It compiles down to less than 3KBytes on ARM. The driver allows board-specific init code to provide platform_data with the relevant MTD partitioning information, and hotplugs. This version has been lightly tested. Its parent at91_dataflash driver has been pretty well banged on, although kernel.org JFFS2 dataflash support was acting broken the last time I tried it.
