DESCRIPTION:A complete open-source TrustZone stack — TF-A at EL3\, OP-TEE
  at Secure EL1\, U-Boot and Linux at EL2 — built from source on the Qual
 comm RB3 Gen2 (QCM6490/Kodiak). \n\nThis talk describes the boot architect
 ure of the platform while walking through the constraints that make this S
 oC non-trivial to bring up: Sectools signing\, running Linux at EL2 withou
 t Gunyah\, QTEE vs OP-TEE  device tree conflicts\, and DSP remoteproc brin
 g-up. \n\nQualcomm Linux ships official support via meta-qcom\, but a mult
 i-hour Yocto build is a poor inner loop for firmware developers\; **a Buil
 droot-based alternative** — integrated into OP-TEE/build.git — enables
  fast iteration at any layer of the stack and live OP-TEE regression testi
 ng\, which will be demonstrated. \n\nWork will be upstreamed to OP-TEE/bui
 ld.git
