ad0d363b8f mtd: OneNAND: Introduce chip_probe function
Samsung SoCs use the own OneNAND controler and detect OneNAND chip at power on.
To use this feature, introduce the chip_probe function.

Also remove workaround for Samsung SoCs.

02ed70bb7b mtd: nand: update nand_default_block_markbad()
This is an update that depends on the previous patches I sent.

We can now write to all the appropriate BB marker locations (i.e.
pages 1 AND 2, bytes 1 AND 6) with nand_default_block_markbad() if
necessary, according to the flags marked in chip->options.

Note that I removed the line:
	ofs += mtd->oobsize;
Unless I am wrong, this line was completely unnecessary in the
first place.

1c3275b656 mtd: nand: davinci: correct 4-bit error correction
On TI's DA830/OMAP-L137, DA850/OMAP-L138 and DM365, after setting the
4BITECC_ADD_CALC_START bit in the NAND Flash control register to 1 and
before waiting for the NAND Flash status register to be equal to 1, 2 or
3, we have to wait till the ECC HW goes to correction state.  Without this
wait, ECC correction calculations will not be proper.

This has been tested on DA830/OMAP-L137, DA850/OMAP-L138, DM355 and DM365
EVMs.

58373ff0af mtd: nand: more BB Detection refactoring and dynamic scan options
This is a revision to PATCH 2/2 that I sent. Link:
http://lists.infradead.org/pipermail/linux-mtd/2010-July/030911.html

Added new flag for scanning of both bytes 1 and 6 of the OOB for
a BB marker (instead of simply one or the other).

The "check_pattern" and "check_short_pattern" functions were updated
to include support for scanning the two different locations in the OOB.

In order to handle increases in variety of necessary scanning patterns,
I implemented dynamic memory allocation of nand_bbt_descr structs
in new function 'nand_create_default_bbt_descr()'. This replaces
some increasingly-unwieldy, statically-declared descriptors. It can
replace several more (e.g. "flashbased" structs). However, I do not
test the flashbased options personally.

How this was tested:

I referenced 30+ data sheets (covering 100+ parts), and I tested a
selection of 10 different chips to varying degrees. Particularly, I
tested the creation of bad-block descriptors and basic BB scanning on
three parts:

ST NAND04GW3B2D, 2K page
ST NAND128W3A, 512B page
Samsung K9F1G08U0A, 2K page

To test these, I wrote some fake bad block markers to the flash (in OOB
bytes 1, 6, and elsewhere) to see if the scanning routine would detect
them properly. However, this method was somewhat limited because the
driver I am using has some bugs in its OOB write functionality.

c7b28e25cb mtd: nand: refactor BB marker detection
Some level of support for various scanning locations was already built in,
but this required clean-up. First, BB marker location cannot be determined
_only_ by the page size. Instead, I implemented some heuristic detection
based on data sheets from various manufacturers (all found in
nand_base.c:nand_get_flash_type()).

Second, once these options were identified, they were not handled properly
by nand_bbt.c:nand_default_bbt(). I updated the static nand_bbt_desc structs
to reflect the need for more combinations of detection. The memory allocation
here probably needs to be done dynamically in the very near future (see next
patches).

NAND_BB_LAST_PAGE used to be in nand.h, but it pertained to bad block
management and so belongs next to NAND_BBT_SCAN2NDPAGE in bbm.h. Also,
its previous flag value (0x00000400) conflicted with NAND_BBT_SCANALLPAGES
so I changed its value to 0x00008000. All uses of the name were modified to
provide consistency with other "NAND_BBT_*" flags.

ac373f7e22 mtd/r852: update card detect early.
This turns out to be the reason for DMA timeouts on resume,
if card was inserted while system was suspended

9489be8ca2 mtd/r852: Fixes in case of DMA timeout
* Don't call complete on dma completion
* do a INIT_COMPLETE before using it each time
* Report DMA read error via ecc 'correct'

I finally managed to make my system do suspend to ram propertly, and I see that
if card was inserted during suspend (while system was off), I get dma timeouts
on resume. Simple card reinsert solves the issue.
This patch solves a crash that would happen otherwise
