	  This enables access to SPI NOR flash, using MT81xx SPI NOR flash

	  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).

	  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

	  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.

	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.
