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). config DM_I2C_COMPAT bool "Enable I2C compatibility layer" depends on DM help Enable old-style I2C functions for compatibility with existing code. This option can be enabled as a temporary measure to avoid needing to convert all code for a board in a single commit. It should not be enabled for any board in an official release. config SYS_I2C_UNIPHIER bool "UniPhier I2C driver" depends on ARCH_UNIPHIER && DM_I2C default y help Support for Panasonic UniPhier I2C controller driver.
