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

config SPI_FLASH_SANDBOX

bool "Support sandbox SPI flash device"
|
|
depends on SANDBOX && DM_SPI_FLASH
|
|
help
|
|
Since sandbox cannot access real devices, an emulation mechanism is
|
|
provided instead. Drivers can be connected up to the sandbox SPI
|
|
bus (see CONFIG_SANDBOX_SPI) and SPI traffic will be routed to this
|
|
device. Typically the contents of the emulated SPI flash device is
|
|
stored in a file on the host filesystem.
