| Simon Glass | f94a1be | 2015-02-05 21:41:35 -0700 | [diff] [blame] | 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). |

| 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. |
