In the case of an erased (sub)page both the data and ECC are all 0xFF
bytes. This fails the normal ECC verification, as the computed ECC of
all-0xFF is not also 0xFF. The GPMC NAND driver attempted to detect
erased pages by checking that the ECC bytes are all-0xFF, but this had
two problems:
1) bitflips in the data were not corrected, so the data looked not-erased
2) bitflips in the ECC bytes were reported as uncorrectable ECC errors
The equivalent Linux driver [1] correctly handles this by counting the
number of 0-bits in the combination of data and ECC bytes. If the number
of 0-bits is less than the amount of bits correctable by the selected
ECC algorithm, then it is treated as an erased page with correctable
bitflips.
Implement similar, though simplified, logic in omap_correct_data_bch().

The DT properties for the "enable-arbiter" and "keep-config" config
knobs were previously named inconsistently:
- The u-boot driver used "nand-enable-arbiter" and "nand-keep-config"
names, without Marvell prefixes.
- The Linux driver uses "marvell,nand-keep-config" ("enable-arbiter"
does not exist anymore in recent kernels, but it also used to be
"marvell,nand-enable-arbiter").
- The device trees almost all use "marvell," prefixed names, except for
one single instance of "nand-enable-arbiter" without vendor prefix.
This commit standardizes on the vendor prefixed version, making the
u-boot driver read from DT props "marvell,nand-enable-arbiter" and
"marvell,nand-keep-config". The one device tree using the unprefixed
version is also changed to use the new naming.
This has the side effect of making the previously no-op "marvell,"
config knobs already present in some DTs actually do something. This was
likely the original intention of the DT authors, but note that this
commit was not tested on every single impacted board.

The original purpose of mtd_erase_callback() in Linux at the time it was
imported to U-Boot, was to inform the caller that erasing is done (since
it was an asynchronous operation).
All supplied callback methods in U-Boot do nothing, but the
mtd_erase_callback() function was (until previous patch) grossly abused
in U-Boot's mtdpart implementation for completely different purpose.
Since we got rid of the abusement, remove the mtd_erase_callback()
function and the .callback member from struct erase_info entirely, in
order to avoid such problems in the future.

nand_dt_init() is still using fdtdec_xx() interface.
If OF_LIVE flag is enabled, dt property can't be get anymore.
Updating all fdtdec_xx() interface to ofnode_xx() to solve this issue.
For doing this, node parameter type must be ofnode.
First idea was to convert "node" parameter to ofnode type inside
nand_dt_init() using offset_to_ofnode(node). But offset_to_ofnode()
is not bijective, in case OF_LIVE flag is enabled, it performs an assert().
So, this leads to update nand_chip struct flash_node field from int to

First set of u-boot-atmel features for the 2021.10 cycle:
This feature set converts the boards pm9261 and pm9263 Ethernet support
to DM; enables hash command for all SAM boards; fixes the NAND pmecc
bit-flips correction; adds Falcon boot for sama5d3_xplained board; and
other minor adjustments.
Not correcting anything in case of empty ECC data area
is not an appropriate strategy, because an uncorrected bit-flip
in an empty sector may cause upper layers (namely UBI) fail to work
properly. Therefore the approach chosen in Linux kernel and other
u-boot mtd drivers has been adopted, where a heuristic implemented
by nand_check_erased_ecc_chunk() is used in order to detect and
correct empty sectors.
Tested with sama5d3_xplained and sam9x60-ek.

The relevant changes to the already existing GD5F1GQ4UExxG support has
been determined by consulting the GigaDevice product change notice
AN-0392-10, version 1.0 from November 30, 2020.
As the overlaps are huge, variable names have been generalized
accordingly.
Apart form the lowered ECC strength (4 instead of 8 bits per 512 bytes),
the new device ID, and the extra quad IO dummy byte, no changes had to
be taken into account.
New hardware features are not supported, namely:
- Power on reset
- Unique ID
- Double transfer rate (DTR)
- Parameter page
- Random data quad IO
The inverted semantic of the "driver strength" register bits, defaulting
to 100% instead of 50% for the Q5 devices, got ignored as the driver has
never touched them anyway.
The no longer supported "read from cache during block erase"
functionality is not reflected as the current SPI NAND core does not
support it anyway.
Implementation has been tested on MediaTek MT7688 based GARDENA smart
Gateways using both, GigaDevice GD5F1GQ5UEYIG and GD5F1GQ4UBYIG.

Currently when marking a block, we use spinand_erase_op() to erase
the block before writing the marker to the OOB area. Doing so without
waiting for the operation to finish can lead to the marking failing
silently and no bad block marker being written to the flash.
In fact we don't need to do an erase at all before writing the BBM.
The ECC is disabled for raw accesses to the OOB data and we don't
need to work around any issues with chips reporting ECC errors as it
is known to be the case for raw NAND.

For reading and writing the bad block markers, spinand->oobbuf is
currently used as a buffer for the marker bytes. During the
underlying read and write operations to actually get/set the content
of the OOB area, the content of spinand->oobbuf is reused and changed
by accessing it through spinand->oobbuf and/or spinand->databuf.
This is a flaw in the original design of the SPI NAND core and at the
latest from 13c15e07eedf ("mtd: spinand: Handle the case where
PROGRAM LOAD does not reset the cache") on, it results in not having
the bad block marker written at all, as the spinand->oobbuf is
cleared to 0xff after setting the marker bytes to zero.
To fix it, we now just store the two bytes for the marker on the
stack and let the read/write operations copy it from/to the page
buffer later.

This name is far too long. Rename it to remove the 'data' bits. This makes

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

Based on Linux kernel commit fc256f5789cb ("mtd: nand: pxa3xx: enable
NAND controller if the SoC needs it"). This commit adds support for the
Armada 8040 nand controller.
The kernel commit says this:
Marvell recent SoCs like A7k/A8k do not boot with NAND flash
controller activated by default. Enabling the controller is a matter
of writing in a system controller register that may also be used for
other NAND related choices.

This member was presumably dropped when this driver was converted from
Linux. However, it is still used in log statements during initialization.
This patch adds the member back. In addition, allocation of struct
vf610_nfc has been moved to the callers of vf610_nfc_nand_init. This allows
it to be allocated by DM (if it is being used) and for dev to be
initialized.

There are too many levels of indirection when calling dev_err. This is an

In a few instances, this patch modifies functions to take an nfc to log

Nand writes should skip the bad blocks with "nand write" command.
In case of bad blocks with above 32-bit address, nand_block_isbad()
returns false due to truncated bad block address.
In below code segment,
if (nand_block_isbad(mtd, offset & ~(mtd->erasesize - 1)))
offset is 64-bit and mtd->erasesize is 32-bit, hence the truncation is
happening. Cast 'mtd->erasesize' with loff_t to fix this issue.

Add SPINAND_HAS_CR_FEAT_BIT flag to identify the SPI NAND device with
the Continuous Read mode.
Some of the Micron SPI NAND devices have the "Continuous Read" feature
enabled by default, which does not fit the subsystem needs.
In this mode, the READ CACHE command doesn't require the starting column
address. The device always output the data starting from the first
column of the cache register, and once the end of the cache register
reached, the data output continues through the next page. With the
continuous read mode, it is possible to read out the entire block using
a single READ command, and once the end of the block reached, the output
pins become High-Z state. However, during this mode the read command
doesn't output the OOB area.
Hence, we disable the feature at probe time.
