behavior.
- Build: No impact.
- Hardware: Affects nucleo-h753zi board.
- Documentation: Add nucleo-h753zi platform
- Security: No impact.
- Compatibility: Backward compatible - adds functionality.
## Testing
Build Host:
- OS: Ubuntu 24.04.4 LTS
- Compiler: arm-none-eabi-gcc 13.2.1
Target:
- Architecture: ARM (STM32H753ZI)
- Board: Nucleo-h753zi
- Configuration: Default nucleo-h753zi:jumbo configuration
Testing performed:
- Connected Ethernet to nucleo-h753zi
