bool "Enable Driver Model for SPI drivers"

help
- If you want to use driver model for SPI drivers, say Y.
- To use legacy SPI drivers, say N.
+ 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.

+ tree fragment from sandbox.dts. It shows that the SPI bus has a
+ single flash device on chip select 0 which is emulated by the driver
+ for "sandbox,spi-flash", which is in drivers/mtd/spi/sandbox.c.
