URL: https://github.com/apache/nuttx/pull/19491
## Summary
Extend stm32h7 HW crypto to support MD5, SHA1, SHA2-224, SHA2-256
accelerations along with their HMAC variants.
## Impact
- User experience: No adaptation required. This fix extends existing
behavior.
- Build: No impact.
- Hardware: No impact.
- Documentation: No impact..
- 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: nucleo-h753zi:crypto configuration
Runtime testing:
Booted, ran crc32, hsash, hmac, aescbc, and aesctr crypto test utilities and
verified HW acceleration is used.
