- * DG2 hardware steppings are a bit unusual. The hardware design was forked to

- * stepping back to "A0" for their first iterations, even though they're more

- * 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

DG2 first production steppings were C0 (for DG2-G10), B1 (for DG2-G11), and A1 (for DG2-G12). Several workarounds that apply onto to pre-production hardware can be dropped. Furthermore, several workarounds that apply to all production steppings can have their conditions simplified to no longer check the GT stepping. Finally, the now-unused IS_DG2_GRAPHICS_STEP macro can be dropped.
