Absolutely not. Again, 70fe23859437ffe4efe0793423937d8b78ebf9d6 says:
"Standard passage provides for a bloblist to be passed from one firmware
phase to the next. That can be used to pass the devicetree along as well.
Add an option to support this.

Tests for this will be added as part of the Universal Payload work."

And your new patch says exactly the same thing, but then:
"Note: This is the correct way to deal with bloblist, since it allows
boards to choose whether they want to use the devicetree from there, or
not." and a large number of patchwork links. And after squashing the
three commits together to see what's being changed, yes, you're
rewriting a whole bunch of the logic without any explanation of why. It
seems to fix 3 Chromebooks and isn't tested on anything else. This is
why I'm saying it's unreviewable.

So no, at the moment I'm inclined to wait for further reports of
problems, and we're coming up on a year since 70fe23859437 was merged,
before making any sort of last-minute change here.
