Hi WolfganG,

I'm not an expert, I just fake it on email ;-).  With that disclaimer, I 
would agree with you WRT all the "find" functions.  The original libfdt 
code does not support any "find" functions, so we will need to add them.

WRT to fdt_find_node_by_path() vs. fdt_path_offset(), I vaguely recall 
some renames happening in the kernel source, but I cannot find them so 
my memory likely is faulty[1].  I would be strongly in favor of 
following the kernel's lead and renaming that function since we are 
already divergent from the original libfdt.  The kernel's name is a much 
better description.

Best regards,

[1] My mind is like a steel trap... unfortunately its been soaking it in 
beer for years now.
