EDAC/i10nm: Add driver decoder for Ice Lake and Tremont CPUs
Current i10nm_edac only supports firmware decoder (ACPI DSM methods).
MCA bank registers of Ice Lake or Tremont CPUs contain the information
to decode DDR memory errors. To get better decoding performance, add
the driver decoder (decoding DDR memory errors via extracting error
information from MCA bank registers) for Ice Lake and Tremont CPUs.
