SPI Support Redundant Boot? (Primary/Secondary Images)

In Tech Ref Figure 19-1 "Boot Flow" it seems to imply that SPI boot will support redundancy.  However, 19.4.8 indiactes it might not, PERSIST_SECONDARY_BOOT, "Used only for boot modes that support redundant boot."  Further, says "The device ROM supports redundant boot for expansion device."  It APPEARS that "expansion device" is limited to SD/MMC which concerns me (SPI not included as an "expansion device").


So...the question is, if I set RCON for SPI Boot and my primary image is corrupt (authentication fails), will it attempt to boot from the secondary SPI image?


Also, I can't find any mention of the authentication process itself.  Could you describe it?


Thanks, Chris
