This patch adds MTD support for the NOR flash on CPCI405 boards.

These boards may have different flash chips installed. Some of them
are detected by the cfi probing. Others need the jedec_probe support.
The patch also adds support for SST39VF3201 chips in jedec_probe.c

The patch is tested with all available flash combinations against
the recent mtd-2.6.git repository.

Matthias
