config SPI_ASPEED_SMC
	tristate "Aspeed flash controllers in SPI mode"
	depends on ARCH_ASPEED || COMPILE_TEST
	depends on HAS_IOMEM && OF
	help
	  This enables support for the Firmware Memory controller (FMC)
	  in the Aspeed AST2500/AST2400 SoCs when attached to SPI NOR chips,
	  and support for the SPI flash memory controller (SPI) for
	  the host firmware. The implementation only supports SPI NOR.

config SPI_HISI_SFC
	tristate "Hisilicon FMC SPI NOR Flash Controller(SFC)"
	depends on ARCH_HISI || COMPILE_TEST
	depends on HAS_IOMEM
	help
	  This enables support for HiSilicon FMC SPI NOR flash controller.

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.

config SPI_INTEL_SPI
	tristate

config SPI_INTEL_SPI_PCI
	tristate "Intel PCH/PCU SPI flash PCI driver (DANGEROUS)"
	depends on X86 && PCI
	select SPI_INTEL_SPI
	help
	  This enables PCI support for the Intel PCH/PCU SPI controller in
	  master mode. This controller is present in modern Intel hardware
	  and is used to hold BIOS and other persistent settings. Using
	  this driver it is possible to upgrade BIOS directly from Linux.

	  Say N here unless you know what you are doing. Overwriting the
	  SPI flash may render the system unbootable.

	  To compile this driver as a module, choose M here: the module
	  will be called intel-spi-pci.

config SPI_INTEL_SPI_PLATFORM
	tristate "Intel PCH/PCU SPI flash platform driver (DANGEROUS)"
	depends on X86
	select SPI_INTEL_SPI
	help
	  This enables platform support for the Intel PCH/PCU SPI
	  controller in master mode. This controller is present in modern
	  Intel hardware and is used to hold BIOS and other persistent
	  settings. Using this driver it is possible to upgrade BIOS
	  directly from Linux.

	  Say N here unless you know what you are doing. Overwriting the
	  SPI flash may render the system unbootable.

	  To compile this driver as a module, choose M here: the module
	  will be called intel-spi-platform.
