| 	  Enable driver model for SPI flash. This SPI flash interface

| 	  (spi_flash_probe(), spi_flash_write(), etc.) is then
 | ||
| 	  implemented by the SPI flash uclass. There is one standard

 | ||
| 	  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
