NLnet pulled their funding for LibreSoC earlier this year with a statement vaguely suggesting that the future of LibreSoC wasn't clear. When you explore the project's web page, it becomes abundantly clear as to why.
It really bums me out too that the project was initially started to address the lack of fully free GPUs. Then later shifted focus to a low power generic SoC, and now this. We are badly in need of a "Raptor Computing Systems" of the GPU space.
