The ONFI NAND device specifies the required ECC correction in its
param page but for non ONFI device, we don't have such info.
The QPIC NAND contoller can use 8 bit ECC if the chip has required
number of spare bytes. This patch calculates the minimum required
spare bytes for using 8 bit ECC and select the same, if non ONFI
device has required number of spare bytes otherwise 4 bit ECC
will be used.

This change is for mounting the rootfs partition in kernel based
on UUID(Universally Unique IDentifier). In embedded system it is
common to store rootfs on SD card or eMMC. Typically the kernel
command line has like: root=/dev/mmcblk0p20 to tell the kernel
where to look for rootfs partition. The problem in this approach
is the eMMC device number can vary based on wether the SD card
present or not in the SD card slot. Also depending on kernel version
the eMMC device number can vary. This means passing the eMMC device
for specifying the rootfs location is not robust approach.
If SD card first get detected then the base minor 0 is assigned to
SD card and kernel will try to mount rootfs from SD card and if
there is no rootfs present on SD card then kernel fail to mount the
rootfs.

Some of the newer nand parts can have bit flips in an erased
page due to the process technology used. In this case, qpic
nand controller is not able to identify that page as an erased
page. In case of bitflips, the ECC engine tries to correct the
data and then it generates the uncorrectable error. Now, this
data is not equal to original raw data.
Following logic is being added to identify the erased
codeword bitflips.
1. Maintain the bitmasks for the codewords which generated
uncorrectable error.
2. Read the raw data again in temp buffer and count the
number of zeros. Since spare bytes are unused in ECC layout and
won’t affect ECC correctability so no need to count number of
zero in spare bytes.
3. If the number of zero is below ECC correctability then it
can be treated as erased CW. In this case, make all the data/oob
of actual user buffers as 0xff.

Following are the major issues in current implementation for
checking the read errors
1. For checking the erased CW, NAND_ERASED_CW_DETECT_STATUS
is being read inside qpic_nand_check_status. The
qpic_nand_check_status will be called after complete page read
so reading status register won’t help in getting the register
value after each CW reads.
2. The mtd layer expects the driver to return non-negative
integer representing the maximum number of bitflips that were
corrected on any one ecc region. The mtd layer takes care of
returning EUCLEAN based on returned number.
3. mtd->ecc_stats is only applicable when ECC engine is
doing ECC correction. For raw reads, the stats should not be
incremented.
Now the changes have been done to reorganize the error handling
1. schedule the NAND_ERASED_CW_DETECT_STATUS reading after
every CW read and check the same if ECC engine generates
uncorrectable error.
2. For raw read, the ECC engine will never generate the
uncorrectable error or erased CW so check only
NAND_FLASH_STATUS.
3. The qpic_nand_read_oob should return the maximum number
of bitflips that were corrected on any one ecc region so
introduce the max_bitflips for maintaining the same.
4. The read should return the complete data in case of
BADMSG so move the BADMSG check in the main read function.

1. ecc strength can be assigned in mtd structure itself so
remove the ecc_width from qpic nand dev structure
2. Initialize bitflip_threshold with 3*4 of ecc strength so
that MTD layer will return EUCLEAN if number of ecc correction
are more than bitflip_threshold.
