mtd: atmel_nand: pmecc: fix bug fail to correct bit error in 1024-bytes sector
The PMECC use BCH algorithm to correct error. In BCH algorithm, the
primitive polynomial value is GF(2^13) for 512-byte
mtd: atmel_nand: pmecc: fix bug fail to correct bit error in 1024-bytes sector
The PMECC use BCH algorithm to correct error. In BCH algorithm, the
primitive polynomial value is GF(2^13) for 512-bytes sector size. And it is
GF(2^14) for 1024-bytes sector size.
This patch will choose correct degree of the remainders (13 or 14) for
different sector size.
Tested in AT91SAM9X5-EK with MLC nand flash.
More detail can be refered to section 5.4.1 of:
AT91SAM ARM-based Embedded MPU Application Note

ARM: at91: atmel_nand: add code to check the ONFI parameter ECC requirement
1. if CONFIG_SYS_NAND_ONFI_DETECTION is defined, driver will check NAND flash's
ecc minimum requirement in ONFI parameter.
a) if CONFIG_PMECC_CAP, CONFIG_PMECC_SECTOR_SIZE are defined. then use it.
Driver will display a WARNING if the values are different from ONFI
parameters.
b) if CONFIG_PMECC_CAP, CONFIG_PMECC_SECTOR_SIZE are not defined, then use
the value from ONFI parameters.
* If ONFI ECC parameters are in ONFI extended parameter page, since we
are not support it, so assume the minimum ecc requirement is 2 bits
in 512 bytes.
* For non-ONFI support nand flash, also assume the minimum ecc
requirement is 2 bits in 512 bytes.
2. if CONFIG_SYS_NAND_ONFI_DETECTION is not defined, just use CONFIG_PMECC_CAP
and CONFIG_PMECC_SECTOR_SIZE.

Using the nand erase option "spread", maybe overwrite
blocks on, for example another mtd partition, if the
erasing range contains bad blocks.
So a limit option is added to nand_erase_opts()

After the fix, If ssize_t i = -1 and size_t l = i + 1, the value of l
will still be 0 as expected.
