   1 * Uploaded QE firmware
   2
   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.

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