Subject: libfdt: a fix but still broken
Date: Thu, 22 Feb 2007 08:27:29 -0500	[thread overview]
Message-ID: <45DD9A41.7060900@smiths-aerospace.com> (raw)

Hi Dave,

I have good news and bad news. ;-)  The good news is that the 
incompatibility between libfdt and jdl's dtc is that libfdt has the name 
offset and the length of the name switched.  booting_without_of.txt says 
the length comes first, so libfdt is in the wrong.

The bad news is that, when I fix this, nearly all of the tests fail (but 
they fail the same way for both tree.S and jdl's dtc).  I have not 
started on that layer of the onion yet.

Best regards,
gvb
