Claude review: gpu: nova: require little endian

Patch Review

**Change:** Adds `depends on !CPU_BIG_ENDIAN` to both `drivers/gpu/drm/nova/Kconfig` and `drivers/gpu/nova-core/Kconfig`, placed after `depends on RUST` in each file.

**Analysis:**

1. **Correctness:** The placement is appropriate -- it follows the existing `depends on` block and comes before the `select` directives, which is consistent with Kconfig style conventions.

2. **Ordering within Kconfig:** Looking at the current tree files, the drm-next tree has slightly different ordering from the patch's context. The current `DRM_NOVA` starts with:
   ```
   depends on 64BIT
   depends on DRM=y
   depends on PCI
   depends on RUST
   ```
   while the patch's context shows:
   ```
   depends on DRM=y
   depends on PCI
   depends on RUST
   ```
   (missing `depends on 64BIT`). This explains why the patches didn't apply cleanly -- the base differs from drm-next. This is a rebase issue, not a patch correctness issue; the base commit `a7a080bb4236` is likely from a different tree. Not a concern for review.

3. **Scope:** Adding the dependency to both `nova-core` and `nova-drm` is correct. Since `DRM_NOVA` selects `NOVA_CORE`, the dependency on `nova-core` alone might seem sufficient, but `select` bypasses dependency checks, so having it explicit on both entries prevents broken configurations.

4. **Commit message:** Clear and well-reasoned. The cover letter discussion about making the endianness decision explicit rather than having "some handling sprinkled around" is a sensible engineering argument.

5. **v1 to v2 delta:** The author correctly dropped the v1 Reviewed-by/Acked-by tags since the patch changed substantively (adding `nova-drm` in addition to `nova-core`).

No issues. The patch is ready to merge (with a trivial rebase onto the appropriate base).
