- 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).
