Key question is not if the platform is popular, but if it is maintained.
The commit log over the last two years strongly suggests that this is
not the case. I suspect that the code is far from compilable at this point,
much less executable. Unfortunately this is hard to verify, as a pre-built
or even buildable toolchain is not easily available.

 From a company perspective, you might want to decide if you want to put
resources into this architecture to keep it alive, or focus on more recent
chips and architectures. Information available on the internet suggests
that Suncore's more recent chips are based on ARM. Given that, it appears
somewhat unlikely that resources for maintaining S+core will be made
available. Guess we'll see if the situation changes.
