If you want to use driver model for I2C drivers, say Y.
To use legacy I2C drivers, say N.
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).
