It is based on fixed-partitions, with some + extensions, but uses 'compatible' to indicate the contents of the node, to + avoid perturbing or confusing existing installations which use 'label' for a + particular purpose. + + Binman supports properties used as inputs to the firmware-packaging process, + such as those which control alignment of partitions. This binding addresses + these 'input' properties. For example, it is common for the 'reg' property + (an 'output' property) to be set by Binman, based on the alignment requested + in the input. + + Once processing is complete, input properties have mostly served their + purpose, at least until the firmware is repacked later, e.g. due to a + firmware update. The 'fixed-partitions' binding should provide enough + information to read the firmware at runtime, including decompression if + needed. + + Documentation for Binman is available at: + + https://u-boot.readthedocs.io/en/latest/develop/package/binman.html + + with the current image-description format at: + + https://u-boot.readthedocs.io/en/latest/develop/package/binman.html#image-description-format + +properties: + compatible: + const: binman + + "#address-cells": + const: 1 + + "#size-cells": + const: 1 + +patternProperties: + "^partition(-.+|@[0-9a-f]+)$": + $ref: partition.yaml + +additionalProperties: false + +examples: + - | + partitions { + compatible = "binman"; + #address-cells = <1>; + #size-cells = <1>; + + partition@100000 { + label = "u-boot"; + reg = <0x100000 0xf00000>; + }; + }; diff --git a/Documentation/devicetree/bindings/mtd/partitions/partitions.yaml b/Documentation/devicetree/bindings/mtd/partitions/partitions.yaml index 1dda2c80747b..849fd15d085c 100644 --- a/Documentation/devicetree/bindings/mtd/partitions/partitions.yaml +++ b/Documentation/devicetree/bindings/mtd/partitions/partitions.yaml @@ -15,6 +15,7 @@ maintainers: oneOf: - $ref: arm,arm-firmware-suite.yaml + - $ref: binman.yaml - $ref: brcm,bcm4908-partitions.yaml - $ref: brcm,bcm947xx-cfe-partitions.yaml - $ref: fixed-partitions.yaml diff --git a/MAINTAINERS b/MAINTAINERS index 2d13bbd69adb..b9441eec979a 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -3542,6 +3542,11 @@ F: Documentation/filesystems/bfs.rst F: fs/bfs/ F: include/uapi/linux/bfs_fs.h +BINMAN +M: Simon Glass +S: Supported +F: Documentation/devicetree/bindings/mtd/partitions/binman* + BITMAP API M: Yury Norov R: Andy Shevchenko -- 2.42.0.758.gaed0368e0e-goog
