Joy!

It looks like the side effect of Grant's improvement just removed all of 
the #ifdefs I hacked into the libfdt primary .c files.

Side note: I was playing last night with the "what if" of deleting (git 
rm libfdt/*.[ch]) all the "standard" libfdt code, then re-importing it. 
  Effectively rebaselining in a kerchunk rather than a patch-forward 
that Kumar has been doing.

The advantages would be:
* It would be clearer that u-boot/libfdt version 2007-11-X == dtc/libfdt 
version 2007-11-X and then we could more easily track changes forward.
* The removal patch is less than 40K (email list limit), but the 
re-import patch is around 70K (IIRC) so that doesn't help.

My current conclusion is that it isn't worth the effort.
* The re-import still has a size vs. email list problem
* Since some libfdt routines changed, other (client) routines must be 
changed at the same time as the re-import (Kumar's patch rolls libfdt 
forward _and_ fixes the handful of calls, so it doesn't have a "broken 
spot" in between patches).

Thanks to all!
