5f94a1bedSSimon Glass	  Enable driver model for I2C. This SPI flash interface
6f94a1bedSSimon Glass	  (spi_flash_probe(), spi_flash_write(), etc.) is then
7f94a1bedSSimon Glass	  implemented by the SPI flash uclass. There is one standard
8f94a1bedSSimon Glass	  SPI flash driver which knows how to probe most chips
9f94a1bedSSimon Glass	  supported by U-Boot. The uclass interface is defined in
10f94a1bedSSimon Glass	  include/spi_flash.h, but is currently fully compatible
11f94a1bedSSimon Glass	  with the old interface to avoid confusion and duplication
12f94a1bedSSimon Glass	  during the transition parent. SPI and SPI flash must be
13f94a1bedSSimon Glass	  enabled together (it is not possible to use driver model
14f94a1bedSSimon Glass	  for one and not the other).

20*4bba9d3fSSimon Glass	  Enable old-style I2C functions for compatibility with existing code.
21*4bba9d3fSSimon Glass	  This option can be enabled as a temporary measure to avoid needing
22*4bba9d3fSSimon Glass	  to convert all code for a board in a single commit. It should not
23*4bba9d3fSSimon Glass	  be enabled for any board in an official release.
