The ONFI command 'parameter page read' needs a non-standard length.
Therefore, we enable the 'length override' field in NDCB0 and set
a non-zero 'length count' in NDCB3.
Additionally, the 'spare enable' bit must be disabled for any command
that sets a non-zero 'length count' in NDCB3.

size is not 512 bytes, then the @ecc_bits is 0xff. The host _SHOULD_ then

1.) Why add the ECC information to the nand_chip{} ?
Each nand chip has its requirement for the ECC correctability, such as
"4bit ECC for each 512Byte" or "40bit ECC for each 1024Byte".
This ECC info is very important to the nand controller, such as gpmi.
Take the Micron MT29F64G08CBABA for example, its geometry is
8KiB page size, 744 bytes oob size and it requires 40bit ECC per 1KiB.
If we do not provide the ECC info to the gpmi nand driver, it has to
calculate the ECC correctability itself. The gpmi driver will gets the 56bit
ECC for per 1KiB which is beyond its BCH's 40bit ecc capibility.
The gpmi will quits in this case. But in actually, the gpmi can supports
this nand chip if it can get the right ECC info.
2.) about the new fields.
The @ecc_strength_ds stands for the ecc bits needed within the @ecc_step_ds.
The two fields should be set from the nand chip's datasheets.
For example:
"4bit ECC for each 512Byte" could be:
@ecc_strength_ds = 4, @ecc_step_ds = 512.
"40bit ECC for each 1024Byte" could be:
@ecc_strength_ds = 40, @ecc_step_ds = 1024.
3.) Why do not re-use the @strength and @size in the nand_ecc_ctrl{}?
The @strength and @size in nand_ecc_ctrl{} is used by the nand controller
driver, while the @ecc_strength_ds and @ecc_step_ds are get from the datasheet.

mtd/tests modules.
The following three functions are used all over the test modules.
- mtdtest_erase_eraseblock()
- mtdtest_scan_for_bad_eraseblocks()
- mtdtest_erase_good_eraseblocks()
The following are wrapper functions for mtd_read() and mtd_write()
which can simplify the return value check.
- mtdtest_read()
- mtdtest_write()
All helpers are put into a single .c file and it will be linked to
every test module later. The code will actually be copied to every
test module, but it is fine for our small test infrastructure.

NAND_BBT_SCANEMPTY is a strange, badly-supported option with omap as its
single remaining user.
NAND_BBT_SCANEMPTY was likely used by accident in omap2[1]. And anyway,
omap2 doesn't scan the chip for bad blocks (courtesy of
NAND_SKIP_BBTSCAN), and so its use of this option is irrelevant.
This patch drops the NAND_BBT_SCANEMPTY option.

nand_base.c shouldn't have to know the implementation details of
nand_bbt's in-memory BBT. Specifically, nand_base shouldn't perform the
bit masking and shifting to isolate a BBT entry.
Instead, just move some of the BBT code into a new nand_markbad_bbt()
interface. This interface allows external users (i.e., nand_base) to
mark a single block as bad in the BBT. Then nand_bbt will take care of
modifying the in-memory BBT and updating the flash-based BBT (if
applicable).

The chip->block_markbad pointer should really only be responsible for
writing a bad block marker for new bad blocks. It should not take care
of BBT-related functionality, nor should it handle bookkeeping of bad
block stats.
This patch refactors the 3 users of the block_markbad interface (plus
the default nand_base implementation) so that the common code is kept in
nand_block_markbad_lowlevel(). It removes some inconsistencies between
the various implementations and should allow for more centralized
improvements in the future.
Because gpmi-nand no longer needs the nand_update_bbt() function, let's
stop exporting it as well.

The parent commit 771c568bcf ("mtd: nand: add

/*
* Note that numblocks is 2 * (real numblocks) here, see i+=2
* below as it makes shifting and masking less painful
*/
I don't think it ever could have been "less painful" to have to shift an
extra bit (or 2, or 3) at various points in nand_bbt.c (and even
outside, since we leak our in-memory format). But now it is certainly
more painful, since we have nice macros and functions to retrieve the
relevant portions of the BBT.
This patch removes any points where the block number is
doubled/halved/otherwise-shifted, instead representing the block number
in its most natural form: as the actual block number.
