offset in u-boot, crashdump data will be stored to flash memory.
Otherwise it will be stored in tftp server.

ipq806x has different alignment of smem_ram_ptable structure when
compared to ipq40xx / ipq807x, which leads to fetching of wrong
information.
This patch addresses the issue by moving the above structure to
board specific.

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.
