File src/soc/amd/common/acpi/dptc.asl:

https://review.coreboot.org/c/coreboot/+/68471/comment/a088dda9_db34770d 
PS71, Line 7: #if CONFIG(FEATURE_DYNAMIC_DPTC)
            : #include <soc/amd/common/acpi/dtts.asl>
> See my comment below. Move this `#if` into the skyrim `dtts. […]

1. In the  skyrim/dsdt.asl  add the following block:
#if CONFIG(FEATURE_DYNAMIC_DPTC)
#include <variant/acpi/dtts.asl>
#endif

2. Then move this file into  src/mainboard/google/skyrim/variants/winterhold/include/variant/acpi/dtts.asl

3. These externals should go into  dtts.asl  since that's what calls them.
