I'm not aware of any significant reverse-engineering efforts for Intel FPGAs. QUIP [1] might be an interesting starting point, but there may be significant IP licensing restrictions surrounding that data.

Out of curiosity, which Xilinx models are you hoping to see support for?

Here is a project to reverse engineer the Xilinx series 7 FPGAs to be able to target them with open source tools:
