For the sake of completeness it was started in 2007 according to the list https://en.wikipedia.org/wiki/Mobile_Internet_device. And - Intel SoFIA (2015) is missing and I don't even know what is used there for platform description. > - Tunnel Creek (2010, DT based) > - A few SpreadTrum SoCs (2017, DT based) > > > but I don't know whether it was set up on ARM or not.
