MTD subsystem (stands for Memory Technology Devices) provides an abstraction layer for raw flash devices. It makes it possible to use the same API when working with different flash types and technologies, e.g. NAND, OneNAND, NOR, AG-AND, ECC'd NOR, etc. MTD subsystem does not deal with block devices like MMC, eMMC, SD, CompactFlash, etc.

The generic NAND driver supports almost all NAND and AG-AND based chips and connects them to the Memory Technology Devices (MTD) subsystem of the Linux Kernel. This documentation is provided for developers who want to implement board drivers or filesystem drivers suitable for NAND devices.

(on/off/module) MTD concatenating support; depends on MTD Support for concatenating several MTD devices into a single (virtual) one. This allows you to have -for example- a JFFS(2) file system spanning multiple physical flash chips. If unsure, say 'Y'. Option: MTD_PARTITIONS Kernel Versions: 2.6.15.6 ... (on/off) MTD partitioning support ...

NAND support in u-boot . Follow the u-boot README. NAND support in kernel Current status . See MTD Driver. Prerequisites . Mainline kernel >= 4.10.0-rc1 NAND detection/initialization patchset patch-v5; Kernel Configuration . To use MTD driver with Linux mainline kernel you should enable:
https://elinux.org/Squashfs_support_for_MTD_subsystem
Squashfs is already widely used on MTD devices (NAND flash etc.) in embedded systems, however, because Squashfs lacks native MTD support, this is currently performed via MTD's block device emulation (or via UBI or stored inside another MTD aware filesystem, i.e. YAFFS2/JFFS2).

To enable Intel Flash support you should have the following selected in the "RAM/ROM/Flash chip drivers" section of the "Memory Technology Devices (MTD)" section Enabling NAND Support. For open source git kernel see NAND configuration. To enable support in the MontaVista TI kernel for NAND Flash you must enable: MTD support; NAND Device Support ...

The MTD code in the linux kernel is updated from MTD CVS in kernel version 2.6.newest only. The MTD CVS works most of the time with kernels from the 2.4 series too. The MTD code which is available in the 2.4 series kernel source is maintainence only and will not be updated, except for bug fixes.
