82f1b86949 drivers: mtd: qpic_nand: Read one complete page for serial trainig
This change will change serial training data read to one complete
page instead of 64-bytes read. Partial page read will cause some

d60219d19c driver: nand: qpic_nand: Fix proper clock source macro in set_clk_rate function.
This change will fix proper clock source macro in set_clk_rate function.
Currently we are passing the wrong value to qpic_set_clk_rate for clock
source.

wrong:
qpic_set_clk_rate(IO_MACRO_CLK_200_MHZ, QPIC_IO_MACRO_CLK, NAND_QSPI_MSTR_CONFIG);

The last argument should be clock source not register base address.

correct:
qpic_set_clk_rate(IO_MACRO_CLK_200_MHZ, QPIC_IO_MACRO_CLK, GPLL0_CLK_SRC);

43b1d16567 driver: nand: qpic_nand: Fix Erase address configuration.
This change will fix erase address configuration for QSPI
nand devices whose density is beyond 128MiB.

To erase a block as per datasheet of serial nand device
page row address <5:0> and the Block row address <16:6>.

In code we are forming directly pages address starting
from <16:0> i.e 17-bit address. Currently we are configuring
address_0 and address_1 register as follws.

addr0 = (page << 16) and addr1 = 0x0;

This logic will work if device size upto 128MiB, but if device
size beyond 128MiB then this logic will fail becasue upper most bit
will go out of add0 register.

Fixing this by changing address configuration logic for erase block.

addr0 = (page << 16) addr1 = (page >> 16) & 0xffff;

a99d538e1b driver: mtd: qpic_nand: Add support for serial training.
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.

599391c231 driver: mtd: qpic: Enable support for page_scope & multi_page read command.
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.

961d3301a2 mtd: nand: qcom: support for non-page aligned read start address
Currently, the nand driver expects the start address to be page
aligned. This patch adds the support for reading data from
non-page aligned start address by using intermediate buffer.

1. Determine the number of pages with start address and
   length.
2. Do the full page read for all the pages. For first page,
   check the start address and determine the column. If column is
   non-zero then use the intermediate buffer for page data and copy
   the required number of bytes from this intermediate buffer to
   actual buffer.

3edd3544f0 mtd: qcom: write NAND_CTRL only once
Currently NAND_CTRL register write generates error.
Register writes to operational registers should always be done
through command descriptors if BAM_MODE is already enabled.
For NAND boot, bootloader already enables BAM_MODE so read the
NAND_CTRL register value and write only if BAM_MODE is not set.

Following error is coming during UBI mount for non ONFI nand
device since mtd->writebufsize is coming as zero

   ubi0: attaching mtd2
   UBI init error 22

The mtd->writebufsize is being assigned currently for ONFI
devices only so move this assigment to common place.

2be258bb00 mtd: nand: qcom: use ECC according chip spare bytes for non ONFI
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.

instead of 256 with standard calculation. This device is non
ONFI/JEDEC device.
