We don't use this carveout on trogdor boards, and having it defined in

OF: reserved mem: OVERLAP DETECTED!
memory@86000000 (0x0000000086000000--0x000000008ec00000) overlaps with memory@8b700000 (0x000000008b700000--0x000000008b710000)
Delete the node in the trogdor dtsi file to fix the overlap problem and
remove the error message.'
Is the mpss_mem node (which defines 0x86000000-0x8ec00000) correct?
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.
I don't actually know... Bjorn, do you?
