The LowRisc project seems to have the mission you're looking for:

"What are the goals of the project? To create a fully open SoC and low-cost development board and to support the open-source hardware community. This will involve volume silicon manufacture..."

They have 2 folks with prior experience on the Rpi team. But, it's hard to tell when they might have something ready. http://lowrisc.org

LowRISC 0.6 was just released which finally has support for RV64GC so you can run Fedora & Debian (ie. real distros!) on it. We're discussing on the mailing list how/when to get the kernel and driver changes upstreamed: https://listmaster.pepperfish.net/pipermail/lowrisc-dev-list... https://listmaster.pepperfish.net/pipermail/lowrisc-dev-list...

The upshot of this is you can run lowRISC 0.6 on something like the Nexys 4 DDR (other FPGAs are available) and have a real Linux distro running on an FPGA, rather slowly and with limited RAM. They even managed to make the ethernet port work using an entirely free stack (though you still unfortunately need Vivado for a while to compile it) and it's a step towards having an ASIC that is completely freely licensed. So it's still baby-steps but I'm glad the lowRISC project came back to life.
