4	bool "Enable Driver Model for SPI flash"
5	depends on DM && DM_SPI
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).

19config SPI_FLASH_SANDBOX
20	bool "Support sandbox SPI flash device"
21	depends on SANDBOX && DM_SPI_FLASH
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.

31	select SPI_MEM
32	help
33	  Enable the SPI flash Core support. This will include basic

35	  erasing through cmd_sf interface.

126	 handed to us in Octal DTR mode. Do not enable this config on flashes
127	 that are not supposed to be handed to U-Boot in Octal DTR mode, even

141	 Some flashes tend to power up with the software write protection
142	 bits set. If this option is set, the whole flash will be unlocked.
143
144	 For legacy reasons, this option default to y. But if you intend to
145	 actually use the software protection bits you should say n here.

223	bool "Use small 4096 B erase sectors"
224	depends on SPI_FLASH
225	default y
226	help
227	  Many flash memories support erasing small (4096 B) sectors. Depending
228	  on the usage this feature may provide performance gain in comparison
229	  to erasing whole blocks (32/64 KiB).
230	  Changing a small part of the flash's contents is usually faster with
231	  small sectors. On the other hand erasing should be faster when using
232	  64 KiB block instead of 16 × 4 KiB sectors.
233
234	  Please note that some tools/drivers/filesystems may not work with
235	  4096 B erase size (e.g. UBIFS requires 15 KiB as a minimum).

240	help
241	  Enable the access for SPI-flash-based AT45xxx DataFlash chips.
242	  DataFlash is a kind of SPI flash. Most AT45 chips have two buffers
243	  in each chip, which may be used for double buffered I/O; but this
244	  driver doesn't (yet) use these for any kind of i/o overlap or prefetching.
245
246	  Sometimes DataFlash is packaged in MMC-format cards, although the
247	  MMC stack can't (yet?) distinguish between MMC and DataFlash
248	  protocols during enumeration.
