As noted here [1], there are potentially future conflicts if we try to
use MTD's "partitions" subnode to describe anything besides just the
fixed-in-the-device-tree partitions currently described in this
document. Particularly, there was a proposal to use this node for the
AFS parser too.
It can pose a (small) problem to try to differentiate the following
nodes:
// using binding as currently specified
partitions {
#address-cells = <x>;
#size-cells = <y>;
partition@0 {
...;
};
};
and
// proposed future binding
partitions {
compatible = "arm,arm-flash-structure";
};
It's especially difficult if other uses of this node start having
subnodes.
So, since the "partitions" node is new in v4.4, let's fixup the binding
before release so that it requires a compatible property, so it's much
clearer to distinguish. e.g.:
// proposed
partitions {
compatible = "fixed-partitions";
#address-cells = <x>;
#size-cells = <y>;
partition@0 {
...;
};
};

pointing readers to Linux code.
Also (although I see this habit repeated throughout the
Documentation/devicetree/bindings/ tree), stop using the title "driver"
in this file, when we're trying explicitly to describe hardware, not
software.

This patch adds support for 4-bit ECC BCH4 for the SPEAr600 SoC. This can
be used by boards equipped with a NAND chip that requires 4-bit ECC
strength. The SPEAr600 HW ECC only supports 1-bit ECC strength.
To enable SW BCH4, you need to specify this in your nand controller
DT node:
nand-ecc-mode = "soft_bch";
nand-ecc-strength = <4>;
nand-ecc-step-size = <512>;
Tested on a custom SPEAr600 board.

In commit 8ff16cf77ce3 ("Documentation: devicetree: m25p80: add "nor-jedec"
binding"), we added a generic "nor-jedec" binding to catch all
mostly-compatible SPI NOR flash which can be detected via the READ ID
opcode (0x9F). This was discussed and reviewed at the time, however
objections have come up since then as part of this discussion:
http://lkml.kernel.org/g/20150511224646.GJ32500@ld-irv-0074
It seems the parties involved agree that "jedec,spi-nor" does a better
job of capturing the fact that this is SPI-specific, not just any NOR
flash.
This binding was only merged for v4.1-rc1, so it's still OK to change
the naming.
At the same time, let's move the documentation to a better name.
Next up: stop referring to code (drivers/mtd/devices/m25p80.c) from the
documentation.

Almost all flash that are "compatible" with m25p80 support the JEDEC
READ ID opcode (0x9F), and in fact, that is often the only thing that is
used to differentiate them. Let's add a compatible string that
represents this lowest common denominator of compatibility.
Device trees can still specify manufacturer/device names in addition,
but (until some reason is found to differentiate between them through
device tree) software will likely want to bind just against the generic
name, and avoid unnecessarily growing its device ID binding tables.
This is related to the work of commit a5b7616c55e1 ("mtd:
m25p80,spi-nor: Fix module aliases for m25p80"), which showed that
maintaining these device tables as stable device-tree/modalias binding
tables is not a worthwhile burden for mostly-comptatible flash.
At the same time, let's update the binding doc to point to the
m25p_ids[] ID list instead of spi_nor_ids[]. The former can be used for
device tree bindings, but the latter cannot. In the future, we should
pare down the m25p_ids[] list to only those IDs which are actually used
in device trees.

Since in SAMA5D4 chip, the PMECC can correct bit flips in erased page.
So we add a DT property to indicate this hardware character.
If the PMECC support correct bitflip erased page (all data are 0xff).
Then we can use the PMECC correct the page and skip the erased page

UBI needs to know the physical erase block size, even on read-only
devices, since it defines the on-device layout. Use a device-tree
provided value to support previously written UBI on read-only NOR.
UBI also needs a non-zero writebufsize, so we set it to one.
Note: This was implemented because hardware write-protected CFI
NOR cannot be probed for the physical erase block size.

If there is no PMECC lookup table stored in ROM, or lookup table offset is
not specified, PMECC driver should build it in DDR by itself.
That make the PMECC driver work for some board which doesn't have PMECC
lookup table in ROM.
The PMECC use the BCH algorithm, so based on the build_gf_tables()
function in lib/bch.c, we can build the Galois Field lookup table.
For more information can refer to section 5.4 of PMECC controller

Pull MTD update from Brian Norris:
"Sorry for delaying this a bit later than usual. There's one mild
regression from 3.16 that was noticed during the 3.17 cycle, and I
meant to send a fix for it along with this pull request. I'll
probably try to queue it up for a later pull request once I've had a
better look at it, hopefully by -rc2 at the latest.
Summary for this pull:
NAND
- Cleanup for Denali driver
- Atmel: add support for new page sizes
- Atmel: fix up 'raw' mode support
- Atmel: miscellaneous cleanups
- New timing mode helpers for non-ONFI NAND
- OMAP: allow driver to be (properly) built as a module
- bcm47xx: RESET support and other cleanups
SPI NOR
- Miscellaneous cleanups, to prepare framework for wider use (some
further work still pending)
- Compile-time configuration to select 4K vs. 64K support for flash
that support both (necessary for using UBIFS on some SPI NOR)
A few scattered code quality fixes, detected by Coverity
See the changesets for more"

Previously, the only way to map a NOR device as a simple ROM was to
use the obsolete "direct-mapped" compatible binding (which further
requires device_type = "nor" and probe-type = "NOR" properties).
This patch adds an "mtd-rom" compatible binding to the "map_rom"
probe type.

Retrieve the NFC clock to make sure it is enabled. Make that optional to ensure
compatibility with previous device trees but document it as mandatory so newer
device trees will include it.

For v3.14 and prior, 1-bit Hamming code ECC via software was the
default choice for some boards e.g. 3430sdp.
Commit ac65caf514ec in v3.15 changed the behaviour
to use 1-bit Hamming code via Hardware using a different ECC layout
i.e. (ROM code layout) than what is used by software ECC.
This ECC layout change causes NAND filesystems created in v3.14
and prior to be unusable in v3.15 and later. So don't mark "sw" scheme
as deperecated and support it.

With a flash-based BBT there is no reason to move the Factory Bad
Block Marker from the data area buffer (to where it is mapped by the
GPMI NAND controller) to the OOB buffer. Thus, make this feature
configurable via DT. This is required for the Ka-Ro electronics
platforms.
In the original code 'this->swap_block_mark' was synonymous with
'!GPMI_IS_MX23()', so use the latter at the relevant places.

- updates for the STMicro "FSM" SPI NOR driver
- fix sync/flush behavior on mtd_blkdevs
