6e9c65d87c mtd: rawnand: onfi: Drop a useless parameter page read 
During detection the logic on the NAND bus is:

    /* Regular ONFI detection */
    1/ read the three NAND parameter pages

    /* Extended parameter page detection */
    2/ send "read the NAND parameter page" commands without reading
       actual data
    3/ move the column pointer to the extended page and read it

If fact, as long as there is nothing happening on the NAND bus between
1/ and 3/, the operation 2/ is redundant so remove it.

1d5d08ee9b mtd: rawnand: onfi: Fix redundancy detection check 
During ONFI detection, the CRC derived from the parameter page and the
CRC supposed to be at the end of the parameter page are compared. If
they do not match, the second then the third copies of the page are
tried.

The current implementation compares the newly derived CRC with the CRC
contained in the first page only. So if this particular CRC area has
been corrupted, then the detection will fail for a wrong reason.

Fix this issue by checking the derived CRC against the right one.

c27075772d mtd: rawnand: marvell: Fix the condition on a return code 
In a previous fix, I changed the condition on which the timeout of an
IRQ is reached from:

    if (!ret)

into:

    if (ret && !pending)

While having a non-zero return code is usual in the Linux kernel, here
ret comes from a wait_for_completion_timeout() which returns 0 when
the waiting period is too long.

Hence, the revised condition should be:

    if (!ret && !pending)

The faulty patch did not produce any error because of the !pending
condition so this change is finally purely cosmetic and does not
change the actual driver behavior.

5756f2e8da mtd: rawnand: denali: add more delays before latching incoming data 
The Denali IP have several registers to specify how many clock cycles
should be waited between falling/rising signals. You can improve the
NAND access performance by programming these registers with optimized
values.

Because struct nand_sdr_timings represents the device requirement
in pico seconds, denali_setup_data_interface() computes the register
values by dividing the device timings with the clock period.

Marek Vasut reported this driver in the latest kernel does not work
on his SOCFPGA board. (The on-board NAND chip is mode 5)

The suspicious parameter is acc_clks, so this commit relaxes it.

The Denali NAND Flash Memory Controller User's Guide describes this
register as follows:

  acc_clks
    signifies the number of bus interface clk_x clock cycles,
    controller should wait from read enable going low to sending
    out a strobe of clk_x for capturing of incoming data.

Currently, acc_clks is calculated only based on tREA, the delay on the
chip side. This does not include additional delays that come from the
data path on the PCB and in the SoC, load capacity of the pins, etc.

This relatively becomes a big factor on faster timing modes like mode 5.

Before supporting the ->setup_data_interface() hook (e.g. Linux 4.12),
the Denali driver hacks acc_clks in a couple of ways [1] [2] to support
the timing mode 5.

We would not go back to the hard-coded acc_clks, but we need to include
this factor into the delay somehow. Let's say the amount of the additional
delay is 10000 pico sec.

In the new calculation, acc_clks is determined by timings->tREA_max +
data_setup_on_host.

Also, prolong the RE# low period to make sure the data hold is met.

Finally, re-center the data latch timing for extra safety.
