This is a slightly modified version of a patch submitted last year by
Reuben Dowle <reuben.dowle@navico.com>. His original comments follow:
This patch adds support for some MLC NAND flashes that place the BB
marker in the LAST page of the bad block rather than the FIRST page used
for SLC NAND and other types of MLC nand.
Lifted from Samsung datasheet for K9LG8G08U0A (1Gbyte MLC NAND):
"
Identifying Initial Invalid Block(s)
All device locations are erased(FFh) except locations where the initial
invalid block(s) information is written prior to shipping. The initial
invalid block(s) status is defined by the 1st byte in the spare area.
Samsung makes sure that the last page of every initial invalid block has
non-FFh data at the column address of 2,048.
...
"
As far as I can tell, this is the same for all Samsung MLC nand, and in
fact the samsung bsp for the processor used in our project (s3c6410)
actually contained a hack similar to this patch but less portable to
enable use of their NAND parts. I discovered this problem when trying to
use a Micron NAND which does not used this layout - I wish samsung would
put their stuff in main-line to avoid this type of problem.
Currently this patch causes all MLC nand with manufacturer codes from
Samsung and ST(Numonyx) to use this alternative location, since these
are the manufactures that I know of that use this layout.

Some of the newer MLC devices have a 6-byte ID sequence in which
several field definitions differ from older chips in a manner that is
not backward compatible. For instance:
Samsung K9GAG08U0M (5-byte sequence): ec d5 14 b6 74
4th byte, bits 1:0 encode the page size: 0=1KiB, 1=2KiB, 2=4KiB, 3=8KiB
4th byte, bits 5:4 encode the block size: 0=64KiB, 1=128KiB, ...
4th byte, bit 6 encodes the OOB size: 0=8B/512B, 1=16B/512B
Samsung K9GAG08U0D (6-byte sequence): ec d5 94 29 34 41
4th byte, bits 1:0 encode the page size: 0=2KiB, 1=4KiB, 3=8KiB, 4=rsvd
4th byte, bits 7;5:4 encode the block size: 0=128KiB, 1=256KiB, ...
4th byte, bits 6;3:2 encode the OOB size: 1=128B/page, 2=218B/page
This patch uses the new 6-byte scheme if the following conditions are
all true:
1) The ID code wraps around after exactly 6 bytes
2) Manufacturer is Samsung
3) 6th byte is zero
The patch also extends the maximum OOB size from 128B to 256B.

The use of a memcpy() during a spinlock operation will cause very long
thread context switch delays if the flash chip bandwidth is low and the
data to be copied large, because a spinlock will disable preemption.
For example: A flash with 6,5 MB/s bandwidth will cause under ubifs,
which request sometimes 128 KiB (the flash erase size), a preemption delay of
20 milliseconds. High priority threads will not be served during this
time, regardless whether this threads access the flash or not. This behavior
breaks real time.
The patch changes all the use of spin_lock operations for xxxx->mutex
into mutex operations, which is exact what the name says and means.
I have checked the code of the drivers and there is no use of atomic
pathes like interrupt or timers. The mtdoops facility will also not be used
by this drivers. So it is dave to replace the spin_lock against mutex.
There is no performance regression since the mutex is normally not
acquired.

This changes the behavier of MTD_OOB_RAW. It used to read both OOB and
data to the data buffer, however you would still need to specify the
dummy oob buffer.
This is only used in one place, but makes it hard to read data+oob
without ECC test, thus I removed that behavier, and fixed the user.
Now MTD_OOB_RAW behaves just like MTD_OOB_PLACE, but doesn't do ECC

What is OTP in OneNAND?
The device includes,
1. one block-sized OTP (One Time Programmable) area and
2. user-controlled 1st block OTP(Block 0)
that can be used to increase system security or to provide
identification capabilities.
What is done?
In OneNAND, one block of the NAND Array is set aside as an OTP
memory area, and 1st Block (Block 0) can be used as OTP area.
This area, available to the user, can be configured and locked
with secured user information. The OTP block can be read,
programmed and locked using the same operations as any other NAND
Flash Array memory block. After issuing an OTP-Lock, OTP block
cannot be erased. OTP block is fully-guaranteed to be a good
block.
Why it is done?
Locking the 1st Block OTP has the effect of a 'Write-protect' to
guard against accidental re-programming of data stored in the 1st
block and OTP Block.
Which problem it solves?
OTP support is provided in the existing implementation of
OneNAND/Flex-OneNAND driver, but it is not working with OneNAND
devices. Have observed the following in current OTP OneNAND Implmentation,
1. DataSheet specific sequence to lock the OTP Area is not followed.
2. Certain functions are quiet generic to cope with OTP specific activity.
This patch re-implements OTP support for OneNAND device.
How it is done?
For all blocks, 8th word is available to the user.
However, in case of OTP Block, 8th word of sector 0, page 0 is reserved as
OTP Locking Bit area. Therefore, in case of OTP Block, user usage on this
area is prohibited. Condition specific values are entered in the 8th word,
sector0, page 0 of the OTP block during the process of issuing an OTP-Lock.
The possible conditions are:
1. Only 1st Block Lock
2. Only OTP Block Lock
3. Lock both the 1st Block and the OTP Block
What Other feature additions have been done in this patch?
This patch adds feature for:
1. Only 1st Block Lock
2. Lock both the 1st Block and the OTP Blocks
Re-implemented OTP support for OneNAND
Added following features to OneNAND
1. Lock only 1st Block in OneNAND
2. Lock BOTH 1st Block and OTP Block in OneNAND
