This patch uses readl and writel instead of in_be32 and
out_be32 for io ops as these internally uses readl,
writel for microblaze and for Zynq, ZynqMP there is
no need of endianness conversion and readl, writel
should work straightaway. This patch starts supporting
the driver for Zynq and ZynqMP platforms.

Several drivers check ->chipsize to see if the third row address cycle
is needed. Instead of embedding magic sizes such as 32MB, 128MB in
drivers, introduce a new flag NAND_ROW_ADDR_3 for clean-up. Since
nand_scan_ident() knows well about the device, it can handle this
properly. The flag is set if the row address bit width is greater
than 16.
Delete comments such as "One more address cycle for ..." because
intention is now clear enough from the code.

Driver are responsible for setting up ECC parameters correctly.
Those include:
- Check if ECC parameters specified (usually by DT) are valid
- Meet the chip's ECC requirement
- Maximize ECC strength if NAND_ECC_MAXIMIZE flag is set
The logic can be generalized by factoring out common code.
This commit adds 3 helpers to the NAND framework:
nand_check_ecc_caps - Check if preset step_size and strength are valid
nand_match_ecc_req - Match the chip's requirement
nand_maximize_ecc - Maximize the ECC strength
To use the helpers above, a driver needs to provide:
- Data array of supported ECC step size and strength
- A hook that calculates ECC bytes from the combination of
step_size and strength.
By using those helpers, code duplication among drivers will be
reduced.

In some cases, nand_do_{read,write}_ops is passed with unaligned
ops->datbuf. Drivers using DMA will be unhappy about unaligned
buffer.
The new struct member, buf_align, represents the minimum alignment
the driver require for the buffer. If the buffer passed from the
upper MTD layer does not have enough alignment, nand_do_*_ops will
use bufpoi.

NAND_ECC_CUSTOM_PAGE_ACCESS
Drivers setting NAND_ECC_CUSTOM_PAGE_ACCESS are supposed to handle the
full read/write page sequence, and waiting for a page to actually be

When changing from one data interface setting to another, one has to
ensure a specific sequence which is described in the ONFI spec.
One of these constraints is that the CE line has go high after a reset
before a command can be sent with the new data interface setting, which
is not guaranteed by the current implementation.
Rework the nand_reset() function and all the call sites to make sure the
CE line is asserted and released when required.
Also make sure to actually apply the new data interface setting on the
first die.

The NAND framework provides several helpers to query timing modes supported
by a NAND chip, but this implies that all NAND controller drivers have
to implement the same timings selection dance. Also currently NAND
devices can be resetted at arbitrary places which also resets the timing
for ONFI chips to timing mode 0.
Provide a common logic to select the best timings based on ONFI or
->onfi_timing_mode_default information. Hook this into nand_reset()
to make sure the new timing is applied each time during a reset.
NAND controller willing to support timings adjustment should just
implement the ->setup_data_interface() method.

When NAND devices are resetted some initialization may have to be done,
like for example they have to be configured for the timing mode that
shall be used. To get a common place where this initialization can be
implemented create a nand_reset() function. This currently only issues
a NAND_CMD_RESET to the NAND device. The places issuing this command
manually are replaced with a call to nand_reset().

The generic NAND DT bindings allows one to tweak the ECC strength and
step size to their need. It can be used to lower the ECC strength to
match a bootloader/firmware config, but might also be used to get a better
reliability.
In the latter case, the user might want to use the maximum ECC strength
without having to explicitly calculate the exact value (this value not
only depends on the OOB size, but also on the NAND controller, and can
be tricky to extract).
Add a generic 'nand-ecc-maximize' DT property and the associated
NAND_ECC_MAXIMIZE flag, to let ECC controller drivers select the best
ECC strength and step-size on their own.
