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

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

245	bool "Use small 4096 B erase sectors"
246	depends on SPI_FLASH
247	default y
248	help
249	  Many flash memories support erasing small (4096 B) sectors. Depending
250	  on the usage this feature may provide performance gain in comparison
251	  to erasing whole blocks (32/64 KiB).
252	  Changing a small part of the flash's contents is usually faster with
253	  small sectors. On the other hand erasing should be faster when using
254	  64 KiB block instead of 16 x 4 KiB sectors.
255
256	  Please note that some tools/drivers/filesystems may not work with
257	  4096 B erase size (e.g. UBIFS requires 15 KiB as a minimum).

263	  Enable the access for SPI-flash-based AT45xxx DataFlash chips.
264	  DataFlash is a kind of SPI flash. Most AT45 chips have two buffers
265	  in each chip, which may be used for double buffered I/O; but this
266	  driver doesn't (yet) use these for any kind of i/o overlap or prefetching.
267
268	  Sometimes DataFlash is packaged in MMC-format cards, although the
269	  MMC stack can't (yet?) distinguish between MMC and DataFlash
270	  protocols during enumeration.
