Delete the node in the trogdor dtsi file to fix the overlap problem and

Is the mpss_mem node (which defines 0x86000000-0x8ec00000) correct?
I think it is. Modem is working for me.
You're right, we don't use that memory on Chrome OS, but I just
wondered whether the other node might also have a problem.
What sort of problem are you thinking about?
At some point in the past I think some of these carved out
areas got updated (perhaps on sdm845?). I.e. they were
wrong, and got corrected later. Some things worked despite
that. So the problem, for example, might be that the
mpss region is bigger than it needs to be.
I don't *assume* there's a problem, I was just asking,
and maybe Bjorn or someone else can verify what's right.
I'm done for the day right now; otherwise I'd spend a
little more time trying to track the information down
myself...

I don't actually know... Bjorn, do you?
