Pull request overview

Note

Copilot was unable to run its full agentic suite in this review.

Ensures the hardware SPDM runner starts from a clean TPM state so capability detection doesn’t fail due to a previously locked/stale TPM state.

Changes:

• Adds a GPIO reset step before TPM detection to clear shared reset-line state.
• Broadens post-job cleanup to run whenever the health check succeeds (not only when a device was detected).
• Makes cleanup unlock/flush commands explicitly error-tolerant when no chip is present.
