This change will fix NULL pointer dereference while reading
from spi nand flash in oobbuf.
The multipage read features is only to read with ecc for
raw read/write the the access is page wise due to mtd layer
will request only one page at a time. So don't increment oobbuf
for every page while reading if already bitflips are present in spi
nand flash. if so data abort will happen due to NULL pointer
dereference.

This change will add support for serial training in
QPIC.
Due to different PNR and PCB delays, serial read data
can come with different delays to QPIC. At high frequency
operations Rx clock should be adjusted according to delays
so that Rx Data can be captured correctly. CLK_CNTR_INIT_VAL_VEC
in NAND_FLASH_SPI_CFG register is a 12-bit vector which is divided
in 4 parts of 3 bits each representing delay of 4 serial input data
lines. Bit [2:0] corresponds to qspi_miso[0], bit [5:3] corresponds
to qspi_miso[1], bit [8:6] corresponds to qspi_miso[2] and bit [11:9]
corresponds to qspi_miso[3]. Delay of each qspi_miso line can be set
from 0 to 7.
For serial training the following rule should be followd.
1) SW should write a page with any known pattern in flash at lower
frequency.
2) Set the CLK_CNTR_INIT_VAL_VEC for qspi_miso[0] line.
3) Read that page repetitively in high frequency mode until it
gets data accurately.
4) Repeat above steps for other qspi_miso lines.

This change will enable page_scope_read & multipage_read support for
QPIC.
QPIC version 2.0 onwards , QPIC support page_scope_read &
multipage_read command to enhance the read performance.
In normal page read command SW is needed to write EXEC_CMD register
for each Code word and collect any Status related to that CW before
issueing EXEC_CMD for next CW.
For page_scope read command SW is required to issue EXEC_CMD
only once for a page. Controller HW takes care of Codeword specific
details and automatically returns status associated with each CW to
BAM pipe, dedicated for status deposition.
enabling all bits in NAND_AUTO_STATUS_EN will require 4 data
descriptors of 24 bytes each. This will publish all NANDc status
registers in system memory.
For multipage_read command SW is required to issue EXEC_CMD only
once for all the pages which configured in QPIC_NAND_MULTI_PAGE_CMD
register.
All interrupts will be operational and valid in these modes.
To check the status for each codeword, it is not possible to access
the status registers while the read command is operational in
page_scope & multi_page read modes. Hence, another feature to publish the
status data (for all NAND status registers) by programming the
NAND_AUTO_STATUS_EN register.
For serial NAND:
Read command for page_scope_read = 0x78800032 (QPIC_NAND_FLASH_CMD)
Read command for multi_page_read = 0x78400032 (QPIC_NAND_FLASH_CMD)
For Parallel NAND:
Read command for page_scope_read = 0x00800032 (QPIC_NAND_FLASH_CMD)
Read command for multi_page_read = 0x00400032 (QPIC_NAND_FLASH_CMD)
Now we fixed maximum data bytes read in one go 128KiB(2KiB page),
256KiB (4KiB page), 512 KiB (8kiB page), because from upper layer
we are getting more than 128KiB data bytes request in one go. if so
just changing the value of "MAX_MULTI_PAGE" macro will increase the
maximum data bytes in one go.
