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.

159 depends on SPI_FLASH
160 default y
161 help
162 Many flash memories support erasing small (4096 B) sectors. Depending
163 on the usage this feature may provide performance gain in comparison
164 to erasing whole blocks (32/64 KiB).
165 Changing a small part of the flash's contents is usually faster with
166 small sectors. On the other hand erasing should be faster when using
167 64 KiB block instead of 16 × 4 KiB sectors.
168
169 Please note that some tools/drivers/filesystems may not work with
170 4096 B erase size (e.g. UBIFS requires 15 KiB as a minimum).

176 Enable the access for SPI-flash-based AT45xxx DataFlash chips.
177 DataFlash is a kind of SPI flash. Most AT45 chips have two buffers
178 in each chip, which may be used for double buffered I/O; but this
179 driver doesn't (yet) use these for any kind of i/o overlap or prefetching.
180
181 Sometimes DataFlash is packaged in MMC-format cards, although the
182 MMC stack can't (yet?) distinguish between MMC and DataFlash
183 protocols during enumeration.
