+ This enables access to most modern SPI flash chips, used for
+ program and data storage. Series supported include Atmel AT26DF,
+ Spansion S25SL, SST 25VF, ST M25P, and Winbond W25X. Other chips
+ are supported as well. See the driver source for the current list,
+ or to add other chips.
+
+ Note that the original DataFlash chips (AT45 series, not AT26DF),
+ need an entirely different driver.
+
+ Set up your spi devices with the right board-specific platform data,
+ if you want to specify device partitioning or to use a device which
+ doesn't support the JEDEC ID instruction.
