| 7 | Enable driver model for SPI flash. This SPI flash interface |
| 8 | (spi_flash_probe(), spi_flash_write(), etc.) is then |
| 9 | implemented by the SPI flash uclass. There is one standard |
| 10 | SPI flash driver which knows how to probe most chips |
| 11 | supported by U-Boot. The uclass interface is defined in |
| 12 | include/spi_flash.h, but is currently fully compatible |
| 13 | with the old interface to avoid confusion and duplication |
| 14 | during the transition parent. SPI and SPI flash must be |
| 15 | enabled together (it is not possible to use driver model |
| 16 | for one and not the other). |

| 21 | help |
| 22 | Since sandbox cannot access real devices, an emulation mechanism is |
| 23 | provided instead. Drivers can be connected up to the sandbox SPI |
| 24 | bus (see CONFIG_SANDBOX_SPI) and SPI traffic will be routed to this |
| 25 | device. Typically the contents of the emulated SPI flash device is |
| 26 | stored in a file on the host filesystem. |

| 93 | Enable the access for SPI-flash-based AT45xxx DataFlash chips. |
| 94 | DataFlash is a kind of SPI flash. Most AT45 chips have two buffers |
| 95 | in each chip, which may be used for double buffered I/O; but this |
| 96 | driver doesn't (yet) use these for any kind of i/o overlap or prefetching. |
| 97 | |
| 98 | Sometimes DataFlash is packaged in MMC-format cards, although the |
| 99 | MMC stack can't (yet?) distinguish between MMC and DataFlash |
| 100 | protocols during enumeration. |
