+         Enable driver model for SPI. The SPI slave interface
+         (spi_setup_slave(), spi_xfer(), etc.) is then implemented by
+         the SPI uclass. Drivers provide methods to access the SPI
+         buses that they control. The uclass interface is defined in
+         include/spi.h. The existing spi_slave structure is attached
+         as 'parent data' to every slave on each bus. Slaves
+         typically use driver-private data instead of extending the
+         spi_slave structure.
