[TF-M] TF-M with Zephyr port of MCUboot

Hi TF-M team,

In our product, we intend to use the vanilla MCUboot (specifically the Zephyr port) instead of the version bundled with Trusted Firmware-M (TF-M).

Since TF-M is optional for our use case, but MCUboot is a mandatory component, we prefer to decouple the two.

Seems there are some provisioning related items that need to be handled in vanilla MCUboot for this type of usage.

We would like to know if you foresee any security concerns or risks associated with this approach? Is this an expected of a usage?

Any feedback for this type of usage would be appreciated.

Thanks Sadik
