c86a4de8df mtd: Add flash_node in struct mtd_info
Currently, add_mtd_partitions_of() can be used only if dev field of
mtd_info struct is populated. It's the case, for example, for a spi nor
flash, which has a DT compatible "jedec,spi-nor" and an associated
device. mtd->dev is populated in spi_nor_scan().

But in case of a raw nand node, mtd_info's dev field can't be populated
as flash node has no compatible, so no associated device.
add_mtd_partitions_of() can't be used to parse "partitions" subnode.

To remove this constraint, add an ofnode field in mtd_info struct
which reference the DT flash node. This new field is populated by
nand_scan_tail(). This new field will be used by add_mtd_partitions_of()
to parse the flash node for "partitions" defined in DT.

ed48490f8d mtd: gpmi: fix the bch setting backward compatible issue
Previous u-boot code changed the default bch setting behavior and caused
backward compatible issue. This fix choose the legacy bch geometry back
again as the default option. If the minimum ecc strength that NAND chips
required need to be chosen, it can be enabled by either adding DT flag
"fsl,use-minimum-ecc" or CONFIG_NAND_MXS_USE_MINIMUM_ECC in configs. The
unused flag "fsl,legacy-bch-geometry" get removed.

Fixes: 51cdf83eea (mtd: gpmi: provide the option to use legacy bch geometry)

f44bcb9f0d nand: gpmc: Handle bitflips in erased pages when using BCH ECC engine
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().

[1] see omap_elm_correct_data() in omap2.c

c03f4da187 mtd: nand: pxa3xx: use marvell, prefix for custom DT properties
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.

0d1ecc99cb mtd: Remove mtd_erase_callback() entirely
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.

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
ofnode and to update all nand_dt_init() callers.

c8c934b910 ti: keystone: Clean up or migrate some NAND related options.
The COFNIG_KEYSTONE_RBL_NAND option is always enabled for the driver on
keystone platforms, but not older davinci platforms.  Use def_bool for
the symbol. For CONFIG_KEYSTONE_NAND_MAX_RBL_PAGE, it's only used within
the driver and derived from another symbol, so remove CONFIG from the
name.  Finally, CONFIG_KEYSTONE_NAND_MAX_RBL_SIZE is a bit more fixed.
For now, use the value directly.  Long term, as part of DM'ifying NAND,
this should come from the device tree.

32cc2368f8 nand: atmel: Correct bitflips in erased pages
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.

783a15b351 mtd: nand: spi: Support GigaDevice GD5F1GQ5UExxG
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.

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

MTD_OPS_PLACE_OOB (0) and spinand_write_to_cache_op() checks for
req.mode != MTD_OPS_AUTO_OOB.

Fix this by explicitly setting req.mode to MTD_OPS_RAW.

987f1e56ed mtd: spinand: Stop using spinand->oobbuf for buffering bad block markers
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.

41575d8e4c dm: treewide: Rename auto_alloc_size members to be shorter
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.

7f36806c9b nand: vybrid: Re-introduce vf610_nfc.dev
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.

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.
