| 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). |

| help |
| Since sandbox cannot access real devices, an emulation mechanism is |
| provided instead. Drivers can be connected up to the sandbox SPI |
| bus (see CONFIG_SANDBOX_SPI) and SPI traffic will be routed to this |
| device. Typically the contents of the emulated SPI flash device is |
| stored in a file on the host filesystem. |
