Yes, that's right.  Support for the old dts-v0 format was removed in
recent upstream dtc versions.  The dts file you have is too new for
the very old ELDK dtc, but too old for current dtc.

Hey jdl, this sort of case is why I was always against removing dts-v0
support.

I concur.  If you really have to use the old kernel, you could
manually update the dts to dts-v1 without making other changes, which
should be relatively simple - that's just a matter of changing all
numbers in the file from bare hex to C-style (decimal by default, 0x
for hex, etc.) and adding the magic /dts-v1/ tag at the top.
