   6         help
   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.

  31           Enable the legacy SPI flash support. This will include basic
  32           standard support for things like probing, read / write, and
  33           erasing through cmd_sf interface.

  92         help
  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.

 108           Enable the MTD support for spi flash layer, this adapter is for
 109           translating mtd_read/mtd_write commands into spi_flash_read/write
 110           commands. It is not intended to use it within sf_cmd or the SPI
 111           flash subsystem. Such an adapter is needed for subsystems like
 112           UBI which can only operate on top of the MTD layer.
