87e92c062b [MTD] cfi_cmdset_0002.c: Add Macronix CFI V1.0 TopBottom detection
This patch adds TopBottom detection for most Macronix chips with CFI V1.0.

The main purpose of this patch is to add detection of the MX29LV400C B
used on the LaCie Ethernet Disk mini V2 NAS.

It detects the following parts correctly:-
MX28F640C3B T
MX29LV002C  B
MX29LV002NC B
MX29LV004C  T
MX29LV400C  T/B
MX29LV800C  T/B
MX29LV160C  T/B
MX29SL800C  T/B
MX29SL802C  T/B

It detects the following uniform part as bottom but it should work
correctly:-
MX29LV040C

For T parts it causes the erase block table to be reversed correctly.
For other parts it avoids the bogus "Assuming top" message.

It does not detect the following correctly:-
MX28F640C3B B
MX29LV002C  T
MX29LV002NC T
MX29LV004C  B
MX29SL400C  T/B
MX29SL402C  T/B

If desired I could supply a more complicated patch to handle these as
well.

Only the MX29LV400C B has been physically tested; others were checked
against their data sheets.

3fc2389847 [MTD] [NAND] Bug on atmel_nand HW ECC : OOB info not correctly written
The functions that write the OOB info (on hardware ECC only) use the 
HW_SYNDROME method.

This is not correct : the start position is "pos = eccsize + chunk" and 
should be eccsize. So, the standard (nand_write_oob_std) function should 
be used. This patch corrects this by using NAND_ECC_HW instead of 
NAND_ECC_HW_SYNDROME.

This has only been tested on small pages nand flash.
(if anyone can test it on large pages that would be great).

13f5369704 [MTD] [NAND] driver extension to support NAND on TQM85xx modules
This patch extends the FSL UPM NAND driver from Anton Vorontsov to
support hardware which does not have the R/B pin of the NAND chip
connected, like the TQM8548 module:

- The OF_GPIO dependency has been removed from the Kconfig option
  because GPIO is not needed. The relevant gpio_* function are then
  stubbed out in <linux/gpio.h>.

- It re-introduces the chip-delay property to define an appropriate
  maximum delay time (tR) required for read operations. The binding
  will be documented in a separate patch.

95ebffd749 [MTD] [NAND] fsl_upm: update driver for the new OF bindings
- Get rid of fsl,wait-pattern and fsl,wait-write. I think this isn't
  chip-specific, and we should always do waits. I saw one board that
  didn't need fsl,wait-pattern, but I assume this was the exception
  that proves the rule;
- Get rid of chip-delay. Today there are no users for this, and if
  anyone really need this they should push the OF bindings beforehand;
- Now flash chips should be child nodes of the FSL UPM NAND controller;
- Implement OF partition parsing.

63fd7f30f3 [MTD] [INFTL] Fix infinite loop in INFTL_foldchain
When iterating over a chain in reverse (oldest block first), this
patch correctly marks the PUtable[] entry of the second to last erase
block of a chain as BLOCK_NIL, regardless of whether or not it can
format the last block successfully. Before, the second to last block
was only marked as pointing to BLOCK_NIL if INFTL_formatblock()
succeeded on the last block of the chain, which could potentially
result in an infinite loop if the block was worn out and refused to
format.

0e4a008a4f UBI: fix IS_ERR test
In case of error, the function add_volume returns an ERR pointer. The
result of IS_ERR, which is supposed to be used in a test as it is, is

43035338ad [MTD] [NAND] pxa3xx_nand: moved nand definitions into shared platform header
This patch moves the exported datastructures from the pxa3xx_nand.c driver
into the <mach/pxa3xx_nand.h> header. This is a plain movement without
any modification of the attributes.

This is the first one of a set of patches which:

 * allows to specify used NAND flash in the platform code and allows to turn
   off the old way to specify NAND characteristics in the driver.  This way did
   not worked well as these characteristics depend on the platform and can not be
   derived from NAND id alone.

   E.g.  some NAND chips share the same ID (e.g.  K9K8G08U0A and K9NBG08U5A) but
   have different timings (which are written in the common driver currently and
   must be modified there).

 * adds 'const' annotations at various places

Further patches will be sent to the mtd-list.

1077be58ad [MTD] [NAND] nand_ecc.c: fix big endian, strengthen test, add printk
This patch for nand_ecc.c fixes three issues

- fix code so it also works on big endian architectures
- added a printk in case of an uncorrectable ecc error
- strengthen the test for correctable errors (decreasing the chance
  that multiple bit faults by accident will be seen as correctable)

Note: the big endian code is only tested in a testbed (running on big endian
hardware) as I cannot rebuild and test a big endian kernel at the moment.
However the only thing that can go wrong is if <asm/byteorder.h> does not
give __BIG_ENDIAN in that case. In my eyes very unlikely.
