menuconfig MTD_SPI_NOR
	tristate "SPI-NOR device support"
	depends on MTD
	help
	  This is the framework for the SPI NOR which can be used by the SPI
	  device drivers and the SPI-NOR device driver.

if MTD_SPI_NOR

config MTD_SPI_NOR_USE_4K_SECTORS
	bool "Use small 4096 B erase sectors"
	default y
	help
	  Many flash memories support erasing small (4096 B) sectors. Depending
	  on the usage this feature may provide performance gain in comparison
	  to erasing whole blocks (32/64 KiB).
	  Changing a small part of the flash's contents is usually faster with
	  small sectors. On the other hand erasing should be faster when using
	  64 KiB block instead of 16 × 4 KiB sectors.

	  Please note that some tools/drivers/filesystems may not work with
	  4096 B erase size (e.g. UBIFS requires 15 KiB as a minimum).

config SPI_FSL_QUADSPI
	tristate "Freescale Quad SPI controller"
	depends on ARCH_MXC
	help
	  This enables support for the Quad SPI controller in master mode.
	  This controller does not support generic SPI. It only supports
	  SPI NOR.

config SPI_NXP_SPIFI
	tristate "NXP SPI Flash Interface (SPIFI)"
	depends on OF && (ARCH_LPC18XX || COMPILE_TEST)
	depends on HAS_IOMEM
	help
	  Enable support for the NXP LPC SPI Flash Interface controller.

	  SPIFI is a specialized controller for connecting serial SPI
	  Flash. Enable this option if you have a device with a SPIFI
	  controller and want to access the Flash as a mtd device.
