MTD updates for v4.13-rc1:
General updates
* Cleanups and additional flash support for "dataflash" driver
* new driver for mchp23k256 SPI SRAM device
* improve handling of MTDs without eraseblocks (i.e., MTD_NO_ERASE)
* refactor and improve "sub-partition" handling with TRX partition
parser; partitions can now be created as sub-partitions of another
partition
SPI NOR updates, from Cyrille Pitchen and Marek Vasut:
* introduce support to the SPI 1-2-2 and 1-4-4 protocols.
* introduce support to the Double Data Rate (DDR) mode.
* introduce support to the Octo SPI protocols.
* add support to new memory parts for Spansion, Macronix and Winbond.
* add fixes for the Aspeed, STM32 and Cadence QSPI controler drivers.
* clean up the st_spi_fsm driver.
NAND updates, from Boris Brezillon:
* addition of on-die ECC support to Micron driver
* addition of helpers to help drivers choose most appropriate ECC
settings
* deletion of dead-code (cached programming and ->errstat() hook)
* make sure drivers that do not support the SET/GET FEATURES command
return ENOTSUPP use a dummy ->set/get_features implementation
returning -ENOTSUPP (required for Micron on-die ECC)
* change the semantic of ecc->write_page() for drivers setting the
NAND_ECC_CUSTOM_PAGE_ACCESS flag
* support exiting 'GET STATUS' command in default ->cmdfunc()
implementations
* change the prototype of ->setup_data_interface()
A bunch of driver related changes:
* various cleanup, fixes and improvements of the MTK driver
* OMAP DT bindings fixes
* support for ->setup_data_interface() in the fsmc driver
* support for imx7 in the gpmi driver
* finalization of the denali driver rework (thanks to Masahiro for the
work he's done on this driver)
* fix "bitflips in erased pages" handling in the ifc driver
* addition of PM ops and dynamic timing configuration to the atmel
driver

Representing flash partitions in devicetree
|
||||
Flash partitions in device tree
|
||||
===============================
|
||||
|
||||
Partitions can be represented by sub-nodes of an mtd device. This can be used
|
||||
Flash devices can be partitioned into one or more functional ranges (e.g. "boot
|
||||
code", "nvram", "kernel").
|
||||
|
||||
Different devices may be partitioned in a different ways. Some may use a fixed
|
||||
flash layout set at production time. Some may use on-flash table that describes
|
||||
the geometry and naming/purpose of each functional region. It is also possible
|
||||
to see these methods mixed.
|
||||
|
||||
To assist system software in locating partitions, we allow describing which
|
||||
method is used for a given flash device. To describe the method there should be
|
||||
a subnode of the flash device that is named 'partitions'. It must have a
|
||||
'compatible' property, which is used to identify the method to use.
|
||||
|
||||
We currently only document a binding for fixed layouts.

||||
Fixed Partitions
|
||||
================
|
||||
|
||||
Partitions can be represented by sub-nodes of a flash device. This can be used
|
||||
on platforms which have strong conventions about which portions of a flash are
|
||||
used for what purposes, but which don't use an on-flash partition table such
|
||||
as RedBoot.
|
||||
|
||||
The partition table should be a subnode of the mtd node and should be named
|
||||
The partition table should be a subnode of the flash node and should be named
|
||||
'partitions'. This node should have the following property:
|
||||
- compatible : (required) must be "fixed-partitions"
|
||||
Partitions are then defined in subnodes of the partitions node.
|
||||

|
||||
For backwards compatibility partitions as direct subnodes of the flash device are
|
||||
supported. This use is discouraged.
|
||||
NOTE: also for backwards compatibility, direct subnodes that have a compatible
|
||||
string are not considered partitions, as they may be used for other bindings.
|
||||
|
||||
#address-cells & #size-cells must both be present in the partitions subnode of the
|
||||
mtd device. There are two valid values for both:
