429866e845 mtd: nand: pxa3xx: set mtd->dev
Currently the pxa3xx driver does not set the udevice in the mtd_info
struct and this prevents the mtd from parsing the partitions via DTS
like for SPI-NOR.

So simply set the mtd->dev to the driver udevice.

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.

a70c3f9fb8 mtd: nand: raw: convert nand_dt_init() to ofnode_xx() interface
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
ofnode and to update all nand_dt_init() callers.

- Support HW ECC(one step is 1KB).
- Support 2 - 32K page size.
- Support 8 CS(depend on SoCs)

Limitations:
- No support for the ecc step size is 512.
- Untested on some SoCs.
- No support for subpages.
- No support for the builtin randomizer.
- The original bad block mask is not supported. It is recommended to

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.

28d476eada ARM: fix LTO for apf27
When apf27_defconfig is built with LTO, linking complains about
undefined reference to `nand_boot`. This is because it is referenced
from inline assembly. Make it visible.

c146de4872 mtd: Update fail_addr when erase fails due to bad blocks
For all other erase failures, the fail_addr is updated with the
failing address. Only in the case of erase failure due to bad block
detection, the fail_addr is not updated. This change simply updates
the fail_addr for this specific scenario so that it is consistent with
the rest of the code.

aa0032f672 spl: fit: nand: allow for non-page-aligned elements
Add a weak nand_get_mtd function for nand drivers to provide mtd info
and use this to set pagesize such that reading of non page-aligned
elements can succeed.

The spl_load_simple_fit already handles block block access so all we
need to do is provide the nand writesize as the block length.

Further cleanup of the drivers which use nand_spl_loaders.c such as
am335x_spl_bch.c, atmel_nand.c, and nand_spl_simple.c could be done
using info from mtd_info instead of statically defined details.

cad6ffa34d mtd: rawnand: fsl_ifc: fix FSL NAND driver to read all ONFI parameter pages
Linux commit a75bbe71a27 ("mtd: rawnand: fsl_ifc: fix FSL NAND driver to
 read all ONFI parameter pages")

Per ONFI specification (Rev. 4.0), if the CRC of the first parameter page
read is not valid, the host should read redundant parameter page copies.
Fix FSL NAND driver to read the two redundant copies which are mandatory
in the specification.

de6f70a632 mtd: spinand: Add WATCHDOG_RESET() in spinand_mtd_read/write()
In case of big area read/write on spi nand, watchdog timeout may occurs.
To fix that, add WATCHDOG_RESET() in spinand_mtd_read() and
spinand_mtd_write() to ensure that watchdog is reset.
