+U-Boot extension board usage (CONFIG_EXTENSION)
+===============================================
+
+Synopsis
+--------
+
+::
+
+    extension scan
+    extension list
+    extension apply <extension number|all>
+
+Description
+-----------
+
+The "extension" command proposes a generic U-Boot mechanism to detect
+extension boards connected to the HW platform, and apply the appropriate
+Device Tree overlays depending on the detected extension boards.
+
+The "extension" command comes with three sub-commands:
+
+ - "extension scan" makes the generic code call the board-specific
+   extension_board_scan() function to retrieve the list of detected
+   extension boards.
+
+ - "extension list" allows to list the detected extension boards.
+
+ - "extension apply <number>|all" allows to apply the Device Tree
+   overlay(s) corresponding to one, or all, extension boards
+
+The latter requires two environment variables to exist:
+
+ - extension_overlay_addr: the RAM address where to load the Device
+   Tree overlays
+
+ - extension_overlay_cmd: the U-Boot command to load one overlay.
+   Indeed, the location and mechanism to load DT overlays is very setup
+   specific.
+
+In order to enable this mechanism, board-specific code must implement
+the extension_board_scan() function that fills in a linked list of
+"struct extension", each describing one extension board. In addition,
+the board-specific code must select the SUPPORT_EXTENSION_SCAN Kconfig
+boolean.
+
+Usage example
+-------------
+
+1. Make sure your devicetree is loaded and set as the working fdt tree.
+
+::
+
+    => run loadfdt
+    => fdt addr $fdtaddr
+
+2. Prepare the environment variables
+
+::
+
+    => setenv extension_overlay_addr 0x88080000
+    => setenv extension_overlay_cmd 'load mmc 0:1 ${extension_overlay_addr} /boot/${extension_overlay_name}'
+
+3. Detect the plugged extension board
+
+::
+
+    => extension scan
+
+4. List the plugged extension board information and the devicetree
+   overlay name
+
+::
+
+    => extension list
+
+5. Apply the appropriate devicetree overlay
+
+For apply the selected overlay:
+
+::
+
+    => extension apply 0
+
+For apply all the overlays:
+
+::
+
+    => extension apply all
+
+Simple extension_board_scan function example
+--------------------------------------------
+
+.. code-block:: c
+
+    int extension_board_scan(struct list_head *extension_list)
+    {
+        struct extension *extension;
+
+        extension = calloc(1, sizeof(struct extension));
+        snprintf(extension->overlay, sizeof(extension->overlay), "overlay.dtbo");
+        snprintf(extension->name, sizeof(extension->name), "extension board");
+        snprintf(extension->owner, sizeof(extension->owner), "sandbox");
+        snprintf(extension->version, sizeof(extension->version), "1.1");
+        snprintf(extension->other, sizeof(extension->other), "Extension board information");
+        list_add_tail(&extension->list, extension_list);
+
+        return 1;
+    }
