With this kind of projects you should always wait and see before endorsing.
When it comes out we should make a judgment by installing a completely free
OS and seeing what works.
That said, the AllWinner processor (SoC) uses the Mali-400 GPU, which is
known to be problematic, as it requires non-free software. There's a reverse
engineering free software project called http://limadriver.org/, and it has
made progress, but I don't know if its usable. But "Chip" can be useful even
without the GPU.
Maybe the WiFi or Bluetooth won't work, but who knows.
About problems with AllWinner in general, I don't think we can endorse any
CPU manufacturer anyway. To me AllWinner don't seem much worse than Intel,
AMD or others, which also distribute and require non-free software for their
hardware to work. So I wouldn't judge the developers of "Chip" just because
they chose to use an AllWinner SoC.
We should wait and see.
