PS1, Line 8: for Winterhold
nit: Unless someone else objects, this can be removed since the file name prefix already indicates this is for winterhold.

Are you booting these devices with these changes also, to ensure the CLs don't break anything?

File src/mainboard/google/skyrim/Kconfig:

PS1, Line 39: 	select SOC_AMD_COMMON_BLOCK_ACPI_DPTC if !BOARD_GOOGLE_MORTHAL
As Karthik pointed out in another CL, this can be moved to `Kconfig.name` and enabled for skyrim and winterhold there.
