This is the Intel SOFIA platform with chips from both Spreadtrum (now
Unisoc) and Rockchips, using a port of the arch/arm/ code DT on x86,

That code was never upstreamed, and is long abandoned by everyone.

The only one I can think of is CONFIG_OLPC, the XO-1 was a Geode LX,
while XO-1.5 used a VIA C7, both with actual open firmware (not just
fdt).
