	help
	  Enable support for the flash hardware.

config SPI_FLASH_W25QXXDV
	bool
	prompt "SPI NOR Flash Winbond W25QXXDV"
	depends on SPI && FLASH

config SPI_FLASH_W25QXXDV_SPI_NAME
	string
	prompt "spi controller device name"

	int
	depends on SPI_FLASH_W25QXXDV
	default 80
	help
	  Device driver initialization priority.
	  Device is connected to SPI bus, it has to
