5 | Enable driver model for I2C. 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). | |

| 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. It should not | |
| 23 | be enabled for any board in an official release. | |
