+	  Enable driver model for I2C. This SPI flash interface
+	  (spi_flash_probe(), spi_flash_write(), etc.) is then
+	  implemented by the SPI flash uclass. There is one standard
+	  SPI flash driver which knows how to probe most chips
+	  supported by U-Boot. The uclass interface is defined in
+	  include/spi_flash.h, but is currently fully compatible
+	  with the old interface to avoid confusion and duplication
+	  during the transition parent. SPI and SPI flash must be
+	  enabled together (it is not possible to use driver model
+	  for one and not the other).
