Thanks for the heads up, this actually fits perfectly my next weeks other
goals.

I'm implementing ECDSA attestation for Enarx next week (i.e. using AESMD).
I was planning to use this branch in any case.

I can combine that with enclaves that trigger backing storage (it can
host arbitarily sized WebAssembly programs). For those changes I'll do
testing both my own hardware (i5-9600KF) and also Icelake Server
(Platinum 8352Y).

If anything comes up, I'll post a fix directly, or if I get stuck I'll
rise up the issues here.

BR, Jarkko
