[PATCH] EDAC/ie31200: Add support for additional Alder Lake-S CPUs

[PATCH] EDAC/ie31200: Add support for additional Alder Lake-S CPUs

[Matt Corallo]

180f091224a002f8bd1629307c34619a5626841e added support for some but
not all Alder Lake-S SoCs. This adds support for, at least,
the i5-12600K which works with the existing Alder Lake-S config.

The commit [1] merged in v6.18-rc1 has already added Alder Lake 
compute die ID for EDAC support.

RE: [PATCH] EDAC/ie31200: Add support for additional Alder Lake-S CPUs

Hi everyone,

There are indeed still missing DIDs for Alder Lake:
0x4650 (6+0, e.g. i5 12500 or 12600)
0x4630 (4+0, e.g. i3 12100E)
0x4610 (2+0, e.g. Pentium Gold G7400E)

The entire Catlow range for low end servers are also not present (Xeon E-2400 and 6300P) 0xA711 to 0xA713

Not sure if there is interest adding in at least 0x4650 which is more commonly used
