Yeah, I saw the patch go by.  I did not recognize the file it patched 
and looked at the history:

     fdt: add decode helper library

     This library provides useful functions to drivers which want to use
     the fdt to control their operation. Functions are provided to:
     :
     :

and the copyright is "Copyright (c) 2011 The Chromium OS Authors."

FDT helper functions have been accumulating in common/fdt_support.c 
rather than a separate file.  Simon, what is the history of 
lib/fdtdec.c?  Is it a shared file from the linux kernel?  If it is 
u-boot specific, it would probably be better to add the functions to 
fdt_support.c.

In the same vein, I also have not looked at the functions provided by 
fdtdec.c to see if there is any overlap with existing fdt_support.c 
functions (a quick look says not).

Best regards,
gvb
