Pull request overview
Adds a new SPEC CPU2017 Linux workload flow under workloads/linux/spec2017, integrating runcpu-based builds from a prepared SPEC workspace, packaging runnable rootfs images, exporting ELFs, and supporting per-case DTB memory profiles during firmware assembly.
Changes:
- Introduce SPEC2017 packaging/build helper (
spec2017-package.py) plus wrapper scripts (build.sh,prepare-spec-workspace.sh) and documentation. - Add Makefile rules to build single cases, ELF-only outputs, and multi-variant exported images (rate/speed, input sets).
- Extend firmware assembly to support DTB memory profiles and enforce minimum DTS-declared memory, plus add SPEC2017-oriented DTS templates.

Add a SPEC2017 workload integration under workloads/linux/spec2017 that builds rate and speed benchmarks from an external SPEC tree with runcpu, stages selected inputs into Linux workload images, and exports firmware, ELF, kernel, and run-script artifacts under the build and image directories. The helper scripts keep SPEC build output inside this repository, add prepare and ELF-only make targets, split multi-command runs into separate exported images, provide mode-specific RISC-V GCC configs, and support PROFILING-controlled NEMU traps plus per-case DTB memory profiles.
