Bug description:
  On TI Panda 4430 board with Linux Linaro image:

  http://snapshots.linaro.org/quantal/pre-built/panda/9/panda-
  quantal_developer_20121206-9.img.gz

  Device Tree directory is empty:

  root@linaro-developer:/proc/device-tree# pwd
  /proc/device-tree
  root@linaro-developer:/proc/device-tree# ls -l
  total 0
  root@linaro-developer:/proc/device-tree# 

  However, the device tree related log exists in boot log:
