Streaming Boot - p2

[rstrongMCT]

In Caliptra.md, section Subsystem Boot Flow, (Caliptra-Subsystem-Mode), step #12 states "Caliptra RT FW will authenticate SoC manifest using ....".

• Is the Soc manifest the same as described in Figure 7: firmware image layout.? Update 3/19/25 - Uncovered the SoC manifest format in https://github.com/chipsalliance/caliptra-sw/blob/main-2.x/auth-manifest/README.mdhttps://github.com/chipsalliance/caliptra-sw/blob/main-2.x/auth-manifest/README.md

In step #13, it is stated: "Caliptra RT FW will set the RECOVERY INTERFACE (IFC) to allow BMC’s Recovery Agent (RA) to send the next image (which MUST be MCU image manifest)."

• What is the difference between the SoC manifest and the MCU image manifest?
