In this case why would one prefer to use CAAM when you have standards
compliant TPM-Chip which additionally offers sealing to specific PCR
(integrity measurement) values.
I don't think we can dictate what good/sane solutions are and which are not.
Both CAAM and TPM have pros and cons, I don't see why supporting both is a bad idea.

IMHO allowing only one backend at the same time is a little over simplified.
It is, but I'd rather leave this until it's actually needed.
What can be done now is adopting a format for the exported keys that would
make this extension seamless in future.

As long we don't make multiple backends at runtime impossible I'm
fine and will happily add support for it when needed. :-)
Thanks,
