+	  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.
