+DTB binding for FCONF properties
+================================
+
+This document describes the device tree format of |FCONF| properties. These
+properties are not related to a specific platform and can be queried from
+common code.
+
+Dynamic configuration
+~~~~~~~~~~~~~~~~~~~~~
+
+The |FCONF| framework expects a *dtb-registry* node with the following field:
+
+- compatible [mandatory]
+   - value type: <string>
+   - Must be the string "fconf,dyn_cfg-dtb_registry".
+
+Then a list of subnodes representing a configuration |DTB|, which can be used
+by |FCONF|. Each subnode should be named according to the information it
+contains, and must be formed with the following fields:
+
+- load-address [mandatory]
+    - value type: <u64>
+    - Physical loading base address of the configuration.
+
+- max-size [mandatory]
+    - value type: <u32>
+    - Maximum size of the configuration.
+
+- id [mandatory]
+    - value type: <u32>
+    - Image ID of the configuration.
+
+- ns-load-address [optional]
+    - value type: <u64>
+    - Physical loading base address of the configuration in the non-secure
+      memory.
+      Only needed by those configuration files which require being loaded
+      in secure memory (at load-address) as well as in non-secure memory
+      e.g. HW_CONFIG
