	tristate "Mediatek MT81xx SPI NOR flash controller"
	depends on HAS_IOMEM
	help
	  This enables access to SPI NOR flash, using MT81xx SPI NOR flash
	  controller. This controller does not support generic SPI BUS, it only
	  supports SPI NOR Flash.

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).

	depends on OF && HAS_IOMEM
	help
	  This enables support for the Quad SPI controller in master mode.
	  This driver does not support generic SPI. The implementation only
	  supports SPI NOR.

config SPI_CADENCE_QUADSPI
	tristate "Cadence Quad SPI controller"
	depends on OF && ARM
	help
	  Enable support for the Cadence Quad SPI Flash controller.

	  Cadence QSPI is a specialized controller for connecting an SPI
	  Flash over 1/2/4-bit wide bus. Enable this option if you have a
	  device with a Cadence QSPI controller and want to access the
	  Flash as an MTD device.

	  This enables support for the Quad SPI controller in master mode.
	  This controller does not support generic SPI. It only supports
	  SPI NOR.

	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.

config SPI_FSL_FLEXSPI
	tristate "Freescale Flex SPI controller"

	  This enables support for the Flex SPI controller in master mode.
	  We only connect the NOR to this controller now.
