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

Enable old-style I2C functions for compatibility with existing code.

This option can be enabled as a temporary measure to avoid needing
|
|
to convert all code for a board in a single commit. It should not
|
|
be enabled for any board in an official release.
