we can't separate ECC from normal data input/output in our NFC, so our DMA

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.

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).
