   4 Subject: [PATCH] brcmfmac: Set board_type used for nvram file selection to
   5  machine-compatible
   6
   7 For of/devicetree using machines, set the board_type used for nvram file
   8 selection to the first string listed in the top-level's node compatible
   9 string, aka the machine-compatible as used by of_machine_is_compatible().
  10
  11 The board_type setting is used to load the board-specific nvram file with
  12 a board-specific name so that we can ship files for each supported board
  13 in linux-firmware.
