	bool "Create NAND FLASH block driver"
	depends on MTD && MTD_NAND
	---help---
		Create the MTD driver for the NAND and "wrap" the NAND as a standard
		block driver that could then, for example, be mounted using FAT or
		any other file system.  Any file system may be used, but there will
		be no wear-leveling.

		NOTE: This options is not currently recommended.  There is not now
		NuttX file system that can handle the NAND back blocks or performs
		wear-leveling other than NXFFS and NXFFS does not use a block driver
		but, rather, operates directly upon the NAND MTD device.

config SAMA5D3XPLAINED_NAND_NXFFS
	bool "Create NAND FLASH NXFFS file system"
	depends on MTD && MTD_NAND && FS_NXFFS && NXFFS_NAND
	---help---
		Create the MTD driver for the NAND and mount the NAND device as
		a wear-leveling, NuttX FLASH file system (NXFFS).  The downside of
		NXFFS is that it can be very slow.

		NOTE: NXFFS is recommended because (1) it can handle the NAND back
		blocks and (1) performs wear-leveling.
