4 bool "Enable Driver Model for SPI flash"
5 depends on DM && DM_SPI
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).
18 config SPI_FLASH_SANDBOX
19 bool "Support sandbox SPI flash device"
20 depends on SANDBOX && DM_SPI_FLASH
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.
29 bool "Legacy SPI Flash Interface support"
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.
