CV-Bowen opened a new pull request, #18005:
URL: https://github.com/apache/nuttx/pull/18005
## Summary
Clean up RPMSG driver header file includes by removing unnecessary OpenAMP
internal header includes and simplifying build configuration.
This change improves code organization and build system clarity by:
- Removing redundant include paths from CMake and Make build files
- Eliminating direct includes of `rpmsg/rpmsg_internal.h` from driver source
files
- Centralizing the internal header include in the public API header
## Impact
No functional changes - purely refactoring header includes
## Testing
qemu-armv8a:rpserver and rpproxy
