- Added build_hp_rtthread.py for building the RT-Thread kernel with RV64 support. - Updated build_hp_smoke.py to target RV64 architecture and modified output filenames. - Modified generate_vexiiriscv.py to reflect RV64 configuration and memory management. - Created hp_tools.py for shared utilities related to RV64 builds. - Enhanced package_hp_boot.py to package RV64 workloads and updated versioning. - Implemented run_hp_sim.py for executing and validating HP workloads with specific markers. - Developed setup_hp_rtthread.py for installing RT-Thread source and environment setup. - Updated GenerateRetroSocHp.scala to generate RV64 application cores. - Enhanced tests for HP boot bundles, platform specifications, and tool utilities to accommodate RV64 changes. - Adjusted test cases to validate new workload types and ensure compatibility with RV64 architecture.
