True. From a commercial point of view this is a huge problem casued
by the device tree - custumers who used to oder a BSP from commercial
service providers (like Robert or me :-) now often find that all they
need to do is to tweak the device tree to get their system running.
Lost business. D*mn... [Maybe this explains Robert's reluctance?]

But as stated before: from the engineering point of view it's a real
big win now.

Best regards,

Wolfgang Denk
