/*
* DG2 hardware steppings are a bit unusual. The hardware design was forked to
* create three variants (G10, G11, and G12) which each have distinct
* workaround sets. The G11 and G12 forks of the DG2 design reset the GT
* stepping back to "A0" for their first iterations, even though they're more
* similar to a G10 B0 stepping and G10 C0 stepping respectively in terms of
* functionality and workarounds. However the display stepping does not reset
* in the same manner --- a specific stepping like "B0" has a consistent
* meaning regardless of whether it belongs to a G10, G11, or G12 DG2.
*
* TLDR: All GT workarounds and stepping-specific logic must be applied in
* relation to a specific subplatform (G10/G11/G12), whereas display workarounds
* and stepping-specific logic will be applied with a general DG2-wide stepping
* number.
