   5     MIPS: BCM47XX: only print SoC name in system type in cpuinfo
   6
   7     Recently the output of "system type" in  /proc/cpuinfo was changed to
   8     Broadcom BCM4730 (Some sample board), but it is better to just print
   9     the SoC name in the "system type" entry. The board name will be added
  10     in the machine entry later.
