The open-source community for gateware is not as large or well-developed as the one for software, but there's many good projects out there.
OpenCores [1] has been around a long time, and there's many high-quality FPGA IP-cores hosted there. The Open Hardware Repository [2] is another good resource. Not all OHWR projects involve FPGAs, but many have full hardware/gateware/software stacks, including the White Rabbit Project [3].
