One never has a second chance to make a first imrpession.
It was easy to make the needed changes (except changing ibm -> amcc, see
below). The dtc does the conversion from the old to the new format dts-v1
without a hitch. Calling "dtc -I dts -O dts hcu5.dts.old >hcu5.dts.new"l
My board is now in even better shape than before as I discovered that in my
dts I even wrongly overwrote a the speed variable for the early boot messages.
Thanks a lot for suggestion!

Can you explain this a little bit more to me. When we started to fabricate our
boards we got the chips (or were it only the even older PPC403?) from IBM. If
I just replace in this dts file "ibm" by "amcc" my board does not boot anymore.
But if you give me a hint where and what I have to replace. I would volunteer
to clean it up (if it not too much work) a little bit.
I cannot test on all boards but I have a walnut, yosemite and sequoia board at
hand. Therefore I would be more confident to limit the cleanup to these boards.
(But only after my vacation, e.g. after the 20 of october).
Would you accept in the mean time a patch which still refers to "ibm,uic"?
Best regards
Niklaus
