|
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).

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.

help
|
|
Enable the legacy SPI flash support. This will include basic
|
|
standard support for things like probing, read / write, and
|
|
erasing through cmd_sf interface.

help

Enable the MTD support for spi flash layer, this adapter is for
|
|
translating mtd_read/mtd_write commands into spi_flash_read/write
|
|
commands. It is not intended to use it within sf_cmd or the SPI
|
|
flash subsystem. Such an adapter is needed for subsystems like
|
|
UBI which can only operate on top of the MTD layer.
