[PATCH] spi: mtd dataflash driver
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.
