Support/Braswell
From GalliumOS Wiki
Intel processors with Braswell SoC's are new and available in a handful of ChromeOS devices. Braswell is positioned as the replacement for BayTrail, so more devices are forthcoming throughout 2016.
Braswell support is in its infancy, the status of which can be seen on the issue tracker here.
Factory firmware support for booting legacy OSes via SeaBIOS is nonexistent, but custom firmware is available for most (all?) Braswell models -- see Firmware.
