File src/soc/intel/tigerlake/fsp_params.c:
https://review.coreboot.org/c/coreboot/+/43980/2/src/soc/intel/tigerlake/fsp...
PS2, Line 119: cpu_id = cpu_get_cpuid();
: if (cpu_id == CPUID_TIGERLAKE_A0)
: params->D3ColdEnable = 0;
: else
we have dedicated variants for ES2 vs. QS SoCs - i.e. A0 vs. B0 silicon. […]
As this is only A0 limitaion, I think it's better handle by devicetree rather than soc code change.
