Yes, but it by no means covers all zen 2 models. See amd-ucode/README
Family=0x17 Model=0x31 Stepping=0x00: Patch=0x0830107a Length=3200 bytes
Family=0x17 Model=0xa0 Stepping=0x00: Patch=0x08a00008 Length=3200 bytes
17-31-00 Rome/Castle Peak 0x0830107a
17-a0-00 Mendocino 0x08a00008
Models missing include:
17-60-01 Renoir 0x0860010b
17-68-01 Lucienne 0x08608105
17-71-00 Matisse 0x08701032
17-90-02 Van Gogh
The known good patch levels are used by xen and linux. But the
microcode for Renoir, Lucienne and Matisse is not available as far as
I can tell.
