Device is connected to SPI bus, it has to be initialized after SPI driver. config SPI_FLASH_W25QXXDV_SPI_FREQ_0 int "SPI system frequency" depends on SPI_FLASH_W25QXXDV default 4 help This option sets the SPI controller's frequency. Beware this value depends on the SPI controller being used and also on the system clock. config SPI_FLASH_W25QXXDV_SPI_SLAVE int "SPI slave linked to SPI flash" depends on SPI_FLASH_W25QXXDV help This option sets the SPI slave number the SPI controller has to switch to when dealing with WinBond SPI flash chip. config SPI_FLASH_W25QXXDV_FLASH_SIZE int "Flash size in bytes" depends on SPI_FLASH_W25QXXDV default 2097152 help This is the flash capacity in bytes. config SPI_FLASH_W25QXXDV_MAX_DATA_LEN int range 1 256 depends on SPI_FLASH_W25QXXDV default 256 help Maximum transmit or receive data length in one user data frame. config SOC_FLASH_QMSI bool prompt "QMSI flash driver" depends on QMSI && FLASH default n help Enable QMSI Quark flash driver. config SOC_FLASH_QMSI_DEV_NAME string "QMSI flash device name" depends on SOC_FLASH_QMSI default "QUARK_FLASH" help Specify the device name for the flash driver. config SOC_FLASH_QMSI_CLK_COUNT_US int "System clk count per microsecond" depends on SOC_FLASH_QMSI default 32 help Specify the system clk cycles per microsecond. config SOC_FLASH_QMSI_WAIT_STATES int "The number of flash wait states" depends on SOC_FLASH_QMSI default 1 help Specify the number of wait states for Quark flash. config SOC_FLASH_QMSI_SYS_SIZE hex "SOC system flash size" depends on SOC_FLASH_QMSI help Specify system flash size on the Quark SOC. config SOC_FLASH_QMSI_API_REENTRANCY bool prompt "flash driver API reentrancy for QMSI shim driver" depends on SOC_FLASH_QMSI default n help Enable support for QMSI flash driver API reentrancy. config SOC_FLASH_NRF5 bool "Nordic Semiconductor nRF5X flash driver" depends on FLASH && SOC_FAMILY_NRF5 default n select FLASH_HAS_PAGE_LAYOUT help Enables Nordic Semiconductor nRF5X flash driver. config SOC_FLASH_NRF5_RADIO_SYNC bool "Nordic nRF5x flash driver synchronized with radio" depends on SOC_FLASH_NRF5 && BT_CTLR default y help Enable synchronization between flash memory driver and radio. config SOC_FLASH_MCUX bool "MCUX flash shim driver" depends on FLASH && HAS_MCUX default n help Enables the MCUX flash shim driver. WARNING: This driver will disable the system interrupts for the duration of the flash erase/write operations. This will have an impact on the overall system performance - whether this is acceptable or not will depend on the use case. config SOC_FLASH_MCUX_DEV_NAME string "MCUX flash device name" depends on SOC_FLASH_MCUX default "MCUX_FLASH" help Specify the device name for the flash driver. source "drivers/flash/Kconfig.stm32" source "drivers/flash/Kconfig.sam0"
