Guys,
And just for the record, here is the QAD script that
I used to verify that all the existing DTS files in
the arch/powerpc/boot/dts directory are byte-identical
before and after my recent modifications. Naturally,
all the DTS files are still in "legacy dts-version 0"
still. But I don't think I broke that mode now. :-)
Feel free to productize or otherwise improve on it...
