This will include basic 7 standard support for things like probing, read / write, and 8 erasing through the MTD layer. 9 10 If unsure, say N 11 12config DM_SPI_FLASH 13 bool "Enable Driver Model for SPI flash" 14 depends on DM && DM_SPI 15 help 16 Enable driver model for SPI flash. This SPI flash interface 17 (spi_flash_probe(), spi_flash_write(), etc.) is then 18 implemented by the SPI flash uclass. There is one standard 19 SPI flash driver which knows how to probe most chips 20 supported by U-Boot. The uclass interface is defined in 21 include/spi_flash.h, but is currently fully compatible 22 with the old interface to avoid confusion and duplication 23 during the transition parent. SPI and SPI flash must be 24 enabled together (it is not possible to use driver model 25 for one and not the other). 26 27config SPI_FLASH_SANDBOX 28 bool "Support sandbox SPI flash device" 29 depends on SANDBOX && DM_SPI_FLASH 30 help 31 Since sandbox cannot access real devices, an emulation mechanism is 32 provided instead. Drivers can be connected up to the sandbox SPI 33 bus (see CONFIG_SANDBOX_SPI) and SPI traffic will be routed to this 34 device. Typically the contents of the emulated SPI flash device is 35 stored in a file on the host filesystem. 36 37endmenu # menu "SPI Flash Support" 38
