Yes, it is called the Equivalence Table and can be found encoded at the top of the AMD microcode containers that Linux distros usually include. I’m only aware of these relations, but maybe there are more:
{
"100F20": [
"100F20",
"100F2A"
],
"100F41": [
"100F41",
"100F52"
],
"100F43": [
"100F43",
"100F53"
],
"100F81": [
"100F81",
"100F91"
]
}
Its possible add a CPU to Microcode by this table

127 is completely left out of the Intel instability story (125 → 129 → 12B).
Probably some test version for OEMs to validate before the “proper” (? ) fixes of 129 and 12B.

Hi folks,
New CPU microcodes for Raptor Lake (P / H / U) Mobile series:
cpuB06A2_platE0_ver00005103_2024-07-29_PRD_4676ABD9
cpuB06A3_platE0_ver00005103_2024-07-29_PRD_4676ABD8
cpuB06A8_platE0_ver00005103_2024-07-29_PRD_4676ABD3
I can’t upload it, because new users don’t have permission. 
Regards.
