> Component Measurement and Authentication (CMA, PCIe r6.2 sec 6.31)
> allows for measurement and authentication of PCIe devices. It is
> based on the Security Protocol and Data Model specification (SPDM,
> https://www.dmtf.org/dsp/DSP0274).
>
> CMA-SPDM in turn forms the basis for Integrity and Data Encryption
> (IDE, PCIe r6.2 sec 6.33) because the key material used by IDE is
> transmitted over a CMA-SPDM session.
>
> As a first step, add support for authentication via a CMA TSM driver.
