Attached is a patch which adds the M25Pxx SPI flash driver.  I've placed
the driver in devs/flash/spi because even though it only currently
supports the Numonyx devices, it should also work with Atmel's AT25DFxx
series and any other compatibles that are out there.  However, I didn't
want to add the Atmel device definitions until the driver has been
properly tested against them.

Headers should be up to date with the new FSF copyright notice and I've
included the ChangeLog files this time ;-)

Chris.
