[PATCH 2/2] schemas: Add a schema for binman

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I am unsure whether to add this with a generic name, such as 'layout',
but for now am using /firmware/binman to avoid conflicts with any other
firmware-layout schema that others might be working on.

+description: |
+  The binman node provides a layout for firmware, used when packaging firmware
+  from multiple projects. For now it just supports a very simple set of
+  features, as a starting point for discussion.
+
+  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:
+  $nodename:
+    const: binman
+
+required:
+  - compatible
+
+additionalProperties: false
+
+examples:
+  - |
+  - |
+    firmware {
+      binman {
+        compatible = "u-boot,binman";
+
+        u-boot {
+          size = <0xa0000>;
+        };
+
+        atf-bl31 {

+title: Binman entry
+
+maintainers:
+  - Simon Glass <sjg@xxxxxxxxxxxx>
+
+description: |
+  The entry node specifies a single entry in the firmware.
+
+  Entries have a specific type, such as "u-boot" or "atf-bl31". If the type
+  is missing, the name is used as the type.
+
+  Note: This definition is intended to be hierarchical, so that entries can
+  appear in other entries. Schema for that is TBD.

+
+  offset:

+      Provides the offset of this entry from the start of its parent section.
+
+  size:
+    $ref: /schemas/types.yaml#/definitions/uint32
+    description: |
+      Provides the size of this entry in bytes.
