+Auxiliary counters
+------------------
+
+FEAT_AMUv1 describes a set of implementation-defined auxiliary counters (also
+known as group 1 counters), controlled by the ``ENABLE_AMU_AUXILIARY_COUNTERS``
+build option.
+
+As a security precaution, Trusted Firmware-A does not enable these by default.
+Instead, platforms may configure their auxiliary counters through one of two
+possible mechanisms:
+
+- |FCONF|, controlled by the ``ENABLE_AMU_FCONF`` build option.
+- A platform implementation of the ``plat_amu_topology`` function (the default).
+
+See :ref:`Activity Monitor Unit (AMU) Bindings` for documentation on the |FCONF|
+device tree bindings.

+Example
+^^^^^^^
+
+An example system offering four cores made up of two clusters, where the cores
+of each cluster share different |AMUs|, may use something like the following:
+
+.. code-block::
+
+    cpus {
+        #address-cells = <2>;
+        #size-cells = <0>;
+
+        amus {
+            amu0: amu-0 {
+                #address-cells = <1>;
+                #size-cells = <0>;
+
+                counterX: counter@0 {
+                    reg = <0>;
+
+                    enable-at-el3;
+                };
+
+                counterY: counter@1 {
+                    reg = <1>;
+
+                    enable-at-el3;
+                };
+            };
+
+            amu1: amu-1 {
+                #address-cells = <1>;
+                #size-cells = <0>;
+
+                counterZ: counter@0 {
+                    reg = <0>;
+
+                    enable-at-el3;
+                };
+            };
+        };
+
+        cpu0@00000 {
+            ...
+
+            amu = <&amu0>;
+        };
+
+        cpu1@00100 {
+            ...
+
+            amu = <&amu0>;
+        };
+
+        cpu2@10000 {
+            ...
+
+            amu = <&amu1>;
+        };
+
+        cpu3@10100 {
+            ...
+
+            amu = <&amu1>;
+        };
+    }
+
+In this situation, ``cpu0`` and ``cpu1`` (the two cores in the first cluster),
+share the view of their AMUs defined by ``amu0``. Likewise, ``cpu2`` and
+``cpu3`` (the two cores in the second cluster), share the view of their |AMUs|
+defined by ``amu1``. This will cause ``counterX`` and ``counterY`` to be enabled
+for both ``cpu0`` and ``cpu1``, and ``counterZ`` to be enabled for both ``cpu2``
+and ``cpu3``.
