   9 Every described BCM4908 board has WP pin not connected. This caused
  10 problems for drivers since day 0 but there was no property to describe
  11 that properly. Projects like OpenWrt were modifying Linux driver to deal
  12 with it.
  13
  14 It's not clear if that is hardware limitation or just reference design
  15 being copied over and over but this applies to all known / supported
  16 BCM4908 boards. Handle it by marking WP as not connected by default.
