+menuconfig MTD_ONENAND
+	tristate "OneNAND Device Support"
+	depends on HAS_IOMEM
+	help
+	  This enables support for accessing all type of OneNAND flash
+	  devices.
+
+if MTD_ONENAND
+
+config MTD_ONENAND_VERIFY_WRITE
+	bool "Verify OneNAND page writes"
+	help
+	  This adds an extra check when data is written to the flash. The
+	  OneNAND flash device internally checks only bits transitioning
+	  from 1 to 0. There is a rare possibility that even though the
+	  device thinks the write was successful, a bit could have been
+	  flipped accidentally due to device wear or something else.
+
+config MTD_ONENAND_GENERIC
+	tristate "OneNAND Flash device via platform device driver"
+	help
+	  Support for OneNAND flash via platform device driver.
+
+config MTD_ONENAND_OMAP2
+	tristate "OneNAND on OMAP2/OMAP3 support"
+	depends on ARCH_OMAP2 || ARCH_OMAP3 || (COMPILE_TEST && ARM)
+	depends on OF || COMPILE_TEST
+	depends on OMAP_GPMC
+	help
+	  Support for a OneNAND flash device connected to an OMAP2/OMAP3 SoC
+	  via the GPMC memory controller.
+	  Enable dmaengine and gpiolib for better performance.
+
+config MTD_ONENAND_SAMSUNG
+	tristate "OneNAND on Samsung SOC controller support"
+	depends on ARCH_S3C64XX || ARCH_S5PV210 || COMPILE_TEST
+	help
+	  Support for a OneNAND flash device connected to Samsung S3C64XX
+	  (using command mapping method) and S5PC110/S5PC210 (using generic
+	  OneNAND method) SoCs.
+	  Choose Y here only if you build for such Samsung SoC.
+
+config MTD_ONENAND_OTP
+	bool "OneNAND OTP Support"
+	help
+	  One Block of the NAND Flash Array memory is reserved as
+	  a One-Time Programmable Block memory area.
+	  Also, 1st Block of NAND Flash Array can be used as OTP.
+
+	  The OTP block can be read, programmed and locked using the same
+	  operations as any other NAND Flash Array memory block.
+	  OTP block cannot be erased.
+
+	  OTP block is fully-guaranteed to be a valid block.
+
+config MTD_ONENAND_2X_PROGRAM
+	bool "OneNAND 2X program support"
+	help
+	  The 2X Program is an extension of Program Operation.
+	  Since the device is equipped with two DataRAMs, and two-plane NAND
+	  Flash memory array, these two component enables simultaneous program
+	  of 4KiB. Plane1 has only even blocks such as block0, block2, block4
+	  while Plane2 has only odd blocks such as block1, block3, block5.
+	  So MTD regards it as 4KiB page size and 256KiB block size
+
+	  Now the following chips support it. (KFXXX16Q2M)
+	    Demux: KFG2G16Q2M, KFH4G16Q2M, KFW8G16Q2M,
+	    Mux:   KFM2G16Q2M, KFN4G16Q2M,
+
+	  And more recent chips
