+       tristate "OneNAND Device Support"
+       depends on MTD
+       depends on HAS_IOMEM
+       help
+         This enables support for accessing all type of OneNAND flash
+         devices. For further information see
+         <http://www.samsung.com/Products/Semiconductor/OneNAND/index.htm>

+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.
+

+       tristate "OneNAND on OMAP2/OMAP3 support"
+       depends on ARCH_OMAP2 || ARCH_OMAP3

+         Support for a OneNAND flash device connected to an OMAP2/OMAP3 CPU
+         via the GPMC memory controller.

+        tristate "OneNAND on Samsung SOC controller support"
+        depends on ARCH_S3C64XX || ARCH_S5PV210 || ARCH_EXYNOS4
+        help
+          Support for a OneNAND flash device connected to an Samsung SOC.
+          S3C64XX uses command mapping method.
+          S5PC110/S5PC210 use generic OneNAND method.
+
+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
