+* Uploaded QE firmware
+
+      If a new firwmare has been uploaded to the QE (usually by the
+      boot loader), then a 'firmware' child node should be added to the QE
+      node.  This node provides information on the uploaded firmware that
+      device drivers may need.
+
+      Required properties:
+      - id: The string name of the firmware.  This is taken from the 'id'
+            member of the qe_firmware structure of the uploaded firmware.
+            Device drivers can search this string to determine if the
+            firmware they want is already present.
+      - extended-modes: The Extended Modes bitfield, taken from the
+                   firmware binary.  It is a 64-bit number represented
+                   as an array of two 32-bit numbers.
+      - virtual-traps: The virtual traps, taken from the firmware binary.
+                  It is an array of 8 32-bit numbers.
+
+Example:
+        firmware {
+                id = "Soft-UART";
+                extended-modes = <0 0>;
+                virtual-traps = <0 0 0 0 0 0 0 0>;
+        };
