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).

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

98 depends on SPI_FLASH
99 default y
100 help
101 Many flash memories support erasing small (4096 B) sectors. Depending
102 on the usage this feature may provide performance gain in comparison
103 to erasing whole blocks (32/64 KiB).
104 Changing a small part of the flash's contents is usually faster with
105 small sectors. On the other hand erasing should be faster when using
106 64 KiB block instead of 16 × 4 KiB sectors.
107
108 Please note that some tools/drivers/filesystems may not work with
109 4096 B erase size (e.g. UBIFS requires 15 KiB as a minimum).

114 help
115 Enable the access for SPI-flash-based AT45xxx DataFlash chips.
116 DataFlash is a kind of SPI flash. Most AT45 chips have two buffers
117 in each chip, which may be used for double buffered I/O; but this
118 driver doesn't (yet) use these for any kind of i/o overlap or prefetching.
119
120 Sometimes DataFlash is packaged in MMC-format cards, although the
121 MMC stack can't (yet?) distinguish between MMC and DataFlash
122 protocols during enumeration.
