Q: what are the target specific fw images that are required to be stitched with SBL?  A: It’s not in SBL boot flow, should be part of stitch process.
Q: how do we update public keys required in build process?  A: 2 methods: (1) statically change during the build phase; (2) change during the stitch phase.
Q: Is there a way to generate vSBL from the open source SBL?   A: Yes, there’s possibility to put vSBL into SBL repo.
Q: In ACRN, Is there any way to let SOS kernel talk with SBL A: No, we don’t encourage SOS kernel to talk with SBL, but SBL can pass necessary information to kernel for its need.
3. All: Community open discussion.
