1* Uploaded QE firmware

3      If a new firmware has been uploaded to the QE (usually by the
4      boot loader), then a 'firmware' child node should be added to the QE
5      node.  This node provides information on the uploaded firmware that
6      device drivers may need.
7
8      Required properties:
9      - id: The string name of the firmware.  This is taken from the 'id'
10            member of the qe_firmware structure of the uploaded firmware.
11            Device drivers can search this string to determine if the
12            firmware they want is already present.
13      - extended-modes: The Extended Modes bitfield, taken from the
14		   firmware binary.  It is a 64-bit number represented
15		   as an array of two 32-bit numbers.
16      - virtual-traps: The virtual traps, taken from the firmware binary.
17		  It is an array of 8 32-bit numbers.

19Example:
20	firmware {
21		id = "Soft-UART";
22		extended-modes = <0 0>;
23		virtual-traps = <0 0 0 0 0 0 0 0>;
24	};
