Dear Grant, Shawn,
I don't this patch is required as m25p** serial flashes are supported
already with generic OF/SPI and OF/MTD schemes.
I have successfully used it myself on an unmodified 2.6.36.3 vanilla
kernel on a xilinx/powerpc platform with a m25p32 part from STM.
You will find attached the corresponding working defconfig + dts files
(appart from partitions which I didn't managed to configure properly...).
Best Regards,
Manuel
