### Duplicate File Analysis
- **Duplicate Groups**: ${duplicates.total_duplicate_groups}

The monthly BSP analysis has detected significant optimization opportunities:

**Wasted Space**: ${(duplicates.total_wasted_space / (1024*1024)).toFixed(1)} MB from duplicate files
**Duplicate Groups**: ${duplicates.total_duplicate_groups}

This represents a significant opportunity for the BSP slimming plan in the RT-Thread 2025 roadmap.

### Recommended Actions:
1. Review the top duplicate files and consider creating shared libraries
2. Consolidate common BSP components into the components/ directory  
3. Implement Kconfig templates for common configurations
4. Remove or compress large unnecessary files
