Introduce the MT8195 Cherry Chromebook platform, including three
revisions of Cherry Tomato boards.
This basic configuration allows to boot Linux on all board revisions
and get a serial console from a ramdisk.

Given that the compatible is "google," I believe we'll want to rename the model
to "Google Tomato", much like was commented on the Asurada series [1], but
better to have confirmation from someone from Google. Chen-Yu? :)
I asked for clarification internally and it turns out we didn't get the
Asurada series quite right either.
Google only owns the reference design, that is Asurada for MT8192 and
Cherry for MT8195. The vendor own the end product design that is based
off of Google's reference design.
So for Tomato, the vendor is Acer. Note that "Tomato" and the other
codenames seen in ChromeOS are public codenames that Google uses.
The compatible string will likely stay "google,XXX", since this is set
in firmware, and updating it after the product has shipped poses both
a significant hurdle and risk.
Yeah, makes sense. Should we call this "Acer Tomato (revX) board" then?
...if we do that, though, we need to know if the other revisions of Tomato
are also from Acer, or we would be getting one right and all the others wrong.
AFAIK each "device build" is its own project and gets its own codename,
otherwise it would get real confusing for us internally really fast.
All clear.
