Enable Secure boot in H6 (Orange Pi3)

[PratikGajera]

Hi Team,

I am very interested to work with H6 SoC especially security feature (secure boot). I explored on google, but i didn't get secure boot related doc. So can you provide me doc where all steps are mentioned like enable secure boot, key loading, image signing, etc. Any help would be appreciable.

Thanks,
Pratik
