Hi Geert,
An aid, though not a full solution, is scripts/dtc/dt_to_config. Though
if I remember correctly, you are already familiar with that. For anyone
who wants more information on the complexities of using dt_to_config, how
to use it, and why it has difficulties providing a precise configuration
automatically, see: http://elinux.org/Device_Tree_presentations_papers_articles#linux_kernel_configuration
slides 33 - 80.
