Project to be presented at XDC 2020 in September:

https://xdc2020.x.org/event/9/contributions/607/

Some questionable statements from the description:

"The core processor design [...] is to be an augmented POWER9 compliant design"

Libre-SOC surely isn't to be a POWER9-compliant design, let alone an augmented one. It is, just like POWER9, to be a PowerISAv3-compliant design.

"This [...] project [...] is also based on [...] the CDC 6600. With help from Mitch Alsup, the designer of the Motorola 68000, it has been possible to upgrade the 6600 core to multi-issue and precise exceptions with no architectural compromises."

According to that web page, Alsup is a designer of the ill-fated 88k, not of any 68k. The 68k designers are listed as:

68000: Stritter, Zolnowsky, Gunter, Leitch, Shustek, Tredennick, Crudele, McAlister, Crisp, Spak, Lee
68010: Zolnowsky, MacGregor
68020: Moyer, Mothersole, Zolnowsky, MacGregor
68030: Boney, MacGregor, Moyer, Lamb, Vegesna, Rupp
68040: Shahan
68060: Circello


Edit: slides available, fortunately without the above-mentioned claims
