DESCRIPTION:In a world where trust is built byte by byte\, measured boot is
  fast becoming the foundation of trust in modern systems. But realizing it
  across a layered\, multi-vendor firmware stack is anything but trivial.\n
 We’ll take a tour through how Arm is enabling a new level of transparenc
 y and integrity weaving together diverse open-source boot-stage components
 \, Trusted Firmware-A (TF-A)\, EDK2\, and Linux\, into a cohesive measured
  boot pipeline. At the heart of this effort is the Firmware Handoff specif
 ication\, acting as the stitching thread\, passing cryptographic measureme
 nts\, metadata\, and control between stages.\nWe’ll trace the flow of me
 asurements from secure world to UEFI to kernel\, and explore how Arm’s p
 latform architecture\, tooling\, and upstream contributions are making thi
 s not just possible\, but practical. Along the way\, we’ll connect the d
 ots to TPM-backed attestation\, event logging\, and remote verification. W
 hether you're a firmware developer\, security architect\, or just a fan of
  elegant handoffs\, join us to see how open firmware is chatting.
