Simon Glassf94a1be2015-02-05 21:41:35 -07005 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.
