* NAND chip and NAND controller generic binding
NAND controller/NAND chip representation:
The NAND controller should be represented with its own DT node, and all
NAND chips attached to this controller should be defined as children nodes
of the NAND controller. This representation should be enforced even for
simple controllers supporting only one chip.
Mandatory NAND controller properties:
- #address-cells: depends on your controller. Should at least be 1 to
encode the CS line id.
- #size-cells: depends on your controller. Put zero unless you need a
mapping between CS lines and dedicated memory regions
Optional NAND controller properties
- ranges: only needed if you need to define a mapping between CS lines and
memory regions
Optional NAND chip properties:
- nand-ecc-mode : String, operation mode of the NAND ecc mode.
Supported values are: "none", "soft", "hw", "hw_syndrome",
"hw_oob_first", "on-die".
Deprecated values:
"soft_bch": use "soft" and nand-ecc-algo instead
- nand-ecc-algo: string, algorithm of NAND ECC.
Valid values are: "hamming", "bch", "rs".
- nand-bus-width : 8 or 16 bus width if not present 8
- nand-on-flash-bbt: boolean to enable on flash bbt option if not present false
- nand-ecc-strength: integer representing the number of bits to correct
per ECC step.
- nand-ecc-step-size: integer representing the number of data bytes
that are covered by a single ECC step.
- nand-ecc-maximize: boolean used to specify that you want to maximize ECC
strength. The maximum ECC strength is both controller and
chip dependent. The controller side has to select the ECC
config providing the best strength and taking the OOB area
size constraint into account.
This is particularly useful when only the in-band area is
used by the upper layers, and you want to make your NAND
as reliable as possible.
- nand-is-boot-medium: Whether the NAND chip is a boot medium. Drivers might use
this information to select ECC algorithms supported by
the boot ROM or similar restrictions.
- nand-rb: shall contain the native Ready/Busy ids.
The ECC strength and ECC step size properties define the correction capability
of a controller. Together, they say a controller can correct "{strength} bit
errors per {size} bytes".
The interpretation of these parameters is implementation-defined, so not all
implementations must support all possible combinations. However, implementations
are encouraged to further specify the value(s) they support.
Example:
nand-controller {
#address-cells = <1>;
#size-cells = <0>;
/* controller specific properties */
nand@0 {
reg = <0>;
nand-ecc-mode = "soft";
nand-ecc-algo = "bch";
/* controller specific properties */
};

Broadcom BCM963XX CFE Loader NOR Flash Partitions
=================================================
Most Broadcom BCM63XX SoC based devices follow the Broadcom reference layout for
NOR. The first erase block used for the CFE bootloader, the last for an
NVRAM partition, and the remainder in-between for one to two firmware partitions
at fixed offsets. A valid firmware partition is identified by the ImageTag
header found at beginning of the second erase block, containing the rootfs and
kernel offsets and sizes within the firmware partition.

Required properties:
- compatible : "allwinner,sun4i-a10-nand".
- reg : shall contain registers location and length for data and reg.
- interrupts : shall define the nand controller interrupt.
- #address-cells: shall be set to 1. Encode the nand CS.
- #size-cells : shall be set to 0.
- clocks : shall reference nand controller clocks.
- clock-names : nand controller internal clock names. Shall contain :
* "ahb" : AHB gating clock
* "mod" : nand controller clock
Optional properties:
- dmas : shall reference DMA channel associated to the NAND controller.
- dma-names : shall be "rxtx".
Optional children nodes:
Children nodes represent the available nand chips.
Optional properties:
- reset : phandle + reset specifier pair
- reset-names : must contain "ahb"
- allwinner,rb : shall contain the native Ready/Busy ids.
- nand-ecc-mode : one of the supported ECC modes ("hw", "soft", "soft_bch" or
"none")
see Documentation/devicetree/bindings/mtd/nand.txt for generic bindings.
Examples:
nfc: nand@1c03000 {
compatible = "allwinner,sun4i-a10-nand";
reg = <0x01c03000 0x1000>;
interrupts = <0 37 1>;
clocks = <&ahb_gates 13>, <&nand_clk>;
clock-names = "ahb", "mod";
#address-cells = <1>;
#size-cells = <0>;
pinctrl-names = "default";
pinctrl-0 = <&nand_pins_a &nand_cs0_pins_a &nand_rb0_pins_a>;
nand@0 {
reg = <0>;
allwinner,rb = <0>;
nand-ecc-mode = "soft_bch";
};
};

help
The ARM Firmware Suite allows the user to divide flash devices into
multiple 'images'. Each such image has a header containing its name
and offset/size etc.
If you need code which can detect and parse these tables, and
register MTD 'partitions' corresponding to each image detected,
enable this option.
You will still need the parsing functions to be called by the driver
for your particular device. It won't happen automatically. The
'physmap' map driver (CONFIG_MTD_PHYSMAP) does this, for example.
