Is this just a comment, or do you oppose Heiko's suggestion?

Other uses of the device tree seem possible and reasonable, too.  For
example, we can use the device tree to configure the firmware (U-Boot
in this case).

Using the device tree  to  describe  the  pin  configuration  of  the
hardware  sounds  easier to me than hard-coding it in some source (or
header) file - no matter if this is  in  the  kernel  and/or  in  the
firmware.

What do you think?

Best regards,

Wolfgang Denk
