For what it's worth, there's current ARM propaganda [huge PDF!] at http://emit.tech/EMiT2016/Adeniyi-Jones-EMiT2016-Barcelona.p... (and incidentally something related to a more interesting sort of ARM-based system from the same meeting: http://emit.tech/EMiT2016/Navaridas-EMiT2016-Barcelona.pdf). That may not be terribly relevant to Fujitsu, though.
