I am looking for a developpement board in order to setup a secure environement.
So I want to use OP-TEE OS for trustzone part (this OS can be Used on the Hikey).
But I have also need secure boot.
So before buy this board , I want to check that all elements are available.
It's seems that Hi6220 SoC specifications are missing.
The best document is http://mirror.lemaker.org/Hi6220V100Multi-Mode_Application_Processor_Function_Description.pdf
But a lot information is missing.
For example , this document talk about a secure boot flag.
But there is nothing about how setup secure boot, key management etc etc.....
Where found true specification of this SoC ?
Without this specification this board is useless for me.
