+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.

+ tristate "Cadence Quad SPI controller"

+ 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.
+
+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.

+ 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.

+ tristate "Intel PCH/PCU SPI flash platform driver (DANGEROUS)"
+ depends on X86
+ select SPI_INTEL_SPI

+ 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.
