Enable driver model for the Chrome OS EC interface. This |
||||
allows the cros_ec SPI driver to operate with CONFIG_DM_SPI |
||||
but otherwise makes few changes. Since cros_ec also supports |
||||
I2C and LPC (which don't support driver model yet), a full |
||||
conversion is not yet possible. |

Enable driver model for SPI flash. 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). |

automatic power-off when the temperature gets too high or low. Other |

devices may be discrete but connected on a suitable bus. |
