This SPI flash interface 6 (spi_flash_probe(), spi_flash_write(), etc.) is then 7 implemented by the SPI flash uclass. There is one standard 8 SPI flash driver which knows how to probe most chips 9 supported by U-Boot. The uclass interface is defined in 10 include/spi_flash.h, but is currently fully compatible 11 with the old interface to avoid confusion and duplication 12 during the transition parent. SPI and SPI flash must be 13 enabled together (it is not possible to use driver model 14 for one and not the other). 15 16config DM_I2C_COMPAT 17 bool "Enable I2C compatibility layer" 18 depends on DM 19 help 20 Enable old-style I2C functions for compatibility with existing code. 21 This option can be enabled as a temporary measure to avoid needing 22 to convert all code for a board in a single commit.
