Ahh, now I see what you were asking.  When I ported libfdt to u-boot, I 
ended up forking it because the official libfdt did not have all the 
functionality we needed and, at the time, David Gibson was not taking 
patches.  He was working on setting up a dual-licensing for libfdt and 
did not want changes before the lawyers were happy with the licensing.

David has since slain the licensing dragon, but we have not unforked libfdt.

To unfork, we have a couple of issues to work out.  One is the amount of 
effort to undo the divergence (probably not bad).  The other is the 
dual-licensing issue: David added a BSD license.  Most of the new code 
is from me, but some is from others (Wolfgang G.) and some of it was 
shamelessly stolen from linux's FDT support (not LIBFDT).  In order to 
unfork, we would have to have agreement from the authors of the 
additional code to relicense with the dual license... or maybe Jon and 
David have independently written equivalent routines (quite possible).

Best regards,
