+Firmware Configuration Framework
+================================
+
+This document provides an overview of the |FCONF| framework.
+
+Introduction
+~~~~~~~~~~~~
+
+The Firmware CONfiguration Framework (|FCONF|) is an abstraction layer for
+platform specific data, allowing a "property" to be queried and a value
+retrieved without the requesting entity knowing what backing store is being used
+to hold the data.
+
+It is used to bridge new and old ways of providing platform-specific data.
+Today, information like the Chain of Trust is held within several, nested
+platform-defined tables. In the future, it may be provided as part of a device
+blob, along with the rest of the information about images to load.
+Introducing this abstraction layer will make migration easier and will preserve
+functionality for platforms that cannot / don't want to use device tree.
+
+Accessing properties
+~~~~~~~~~~~~~~~~~~~~
+
+Properties defined in the |FCONF| are grouped around namespaces and
+sub-namespaces: a.b.property.
+Examples namespace can be:
+
+- (|TBBR|) Chain of Trust data: tbbr.cot.trusted_boot_fw_cert
+- (|TBBR|) dynamic configuration info: tbbr.dyn_config.disable_auth
+- Arm io policies: arm.io_policies.bl2_image
+
+Properties can be accessed with the ``FCONF_GET_PROPERTY(a,b,property)`` macro.
+
+Defining properties
+~~~~~~~~~~~~~~~~~~~
+
+Properties composing the |FCONF| have to be stored in C structures. If another
+backing store is wanted to be used, the platform has to provide a ``populate()``
+function to fill the corresponding C structure.
+
+The ``populate()`` function must be registered to the |FCONF| framework with
+the ``FCONF_REGISTER_POPULATOR()`` macro. This ensures that the function would
+be called inside the generic ``fconf_populate()`` function during
+initialization.
+
+::
+
+    int fconf_populate_tbbr_dyn_config(uintptr_t config)
+    {
+        /* read dtb and fill tbbr_dyn_config struct */
+    }
+
+    FCONF_REGISTER_POPULATOR(fconf_populate_tbbr_dyn_config);
+
+Then, a wrapper has to be provided to match the ``FCONF_GET_PROPERTY()`` macro:
+
+::
+
+    /* generic getter */
+    #define FCONF_GET_PROPERTY(a,b,property)	a##__##b##_getter(property)
+
+    /* my specific getter */
+    #define tbbr__dyn_config_getter(id)	tbbr_dyn_config.id
+
+This second level wrapper can be used to remap the ``FCONF_GET_PROPERTY()`` to
+anything appropriate: structure, array, function, etc..
+
+Loading the property device tree
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The ``fconf_load_config()`` must be called to load the device tree containing
+the properties' values. This must be done after the io layer is initialized, as
+the |DTB| is stored on an external device (FIP).
+
+.. uml:: ../resources/diagrams/plantuml/fconf_bl1_load_config.puml
+
+Populating the properties
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Once a valid device tree is available, the ``fconf_populate(config)`` function
+can be used to fill the C data structure with the data from the config |DTB|.
+This function will call all the ``populate()`` callbacks which have been
+registered with ``FCONF_REGISTER_POPULATOR()``.
+
+.. uml:: ../resources/diagrams/plantuml/fconf_bl2_populate.puml
