In linux kernel since version 2.6.20 (release Date: 2007-02-04)
This provides an MTD device driver for the M-Systems DiskOnChip
Millennium Plus devices.
If you use this device, you probably also want to enable the INFTL
'Inverse NAND Flash Translation Layer' option below, which is used
to emulate a block device by using a kind of file system on the
flash chips.
NOTE: This driver will soon be replaced by the new DiskOnChip driver
under "NAND Flash Device Drivers" (currently that driver does not
support all Millennium Plus devices).
