Hi Joakim,

I looked for the definition of DEFAULT_OF_TREE and it doesn't exist in 
the current u-boot.  I used the gitweb "pickaxe" to look for 
DEFAULT_OF_TREE and didn't find it that way either.  Can you identify 
when we lost the definition?

The problem with your patch is that, if DEFAULT_OF_TREE isn't defined by 
somebody, the builds will break.  Since it is undefined at the moment, 
that means *all* of the OF_FLAT_TREE and OF_LIBFDT builds would break. :-(

Thanks,
gvb
