- Updated fault reference documentation to clarify Linux termination behavior and NPU-P6 requirements. - Enhanced Linux runtime section with emphasis on platform setup and kernel handoff processes. - Revised overview section to include detailed descriptions of NPU capabilities and memory configurations. - Improved product use documentation to specify Linux rootfs behavior and acceptance checkpoints. - Clarified reset summary to differentiate between Linux and smoke/NPU-P6 acceptance processes. - Updated software section to reflect changes in Linux image loading and readiness protocols. - Modified build scripts to support RV64 architecture and ensure proper ELF requirements. - Enhanced NPU compiler to support cycle counting for RV64 and RV32 architectures. - Added tests to validate new configurations and ensure compliance with updated publication contracts.
