There is a mechanism in the following document/link/post that appears to be using an i2c sequence to force a secure boot without permanently burning any fuses - just writing the shadow registers and resetting. Can this be applied on the P1010RDB? It seems to imply it may need some FPGA support?

Generally, I have not been able to find a clear P1010-specific procedure for soft-fused and hard-fused secure boot prototyping and manufacturing that has relatively high level tools (u-boot or linux command line[no register writing or CCS]) for doing everything from code signing thru soft and/or hard fuse burning and testing. I have pieces here and there in the platform manual, the SDK manual, the manufacturing for trust whitepapers - Does anybody know if this exists?
