summary
HPE ports Linux/OpenBMC to a custom GXP BMC ASIC and proves it boots in CI after three years of work; GXP ASIC with silicon root of trust anchors an RSA/SHA384 chain from immutable micro‑boot to U‑Boot. Drivers live in an HPE GitHub fork with the first kernel patches merged but many device drivers remain proof‑of‑concept needing upstreaming. Fleet rollout requires an ownership transfer via signed keys and PMO (USB key option, optional node‑locking), and tooling exists for scripted installs. First kernel patches merged confirms viability.
