This is the most important commit in order for someone who don't deal
that much with ARM TEE to get right. Until this commit is right, I don't
unfortunately have much to say about other commits.

Instead of making disjoint islands, you should edit trusted-encrypted.rst
so that it describes commonalities and differences.

What the document currently describes is the usage model. It could be a
section of its own. In that you should describe first the common
parameters and separetely the backend specific parametrs.

document describe the key generation e.g. is the hardware used and how
it is used, is there salting with krng and so forth.
