 signature verify

Hi, Mimi, Dave

I checked the previous patches:
https://www.spinics.net/lists/keyrings/msg03518.html
https://www.spinics.net/lists/keyrings/msg03517.html
https://www.spinics.net/lists/keyrings/msg03516.html

That the latest patched I could found that placed the platform keyring in certs/
However it didn't cc kexec list, and so I think Dave didn't receive them.

I could compose a patch to use the previous design, how do you think?
