This description covers details we can see in the patch itself. Can you
please rather describe the motivation and any related considerations,
e.g. answer:

 * What devices will you be managing via MCTP?
 * How do they affect the function of the platform?
    - Alternatively, how does _not_ having the MCTP capability to manage
      them impact the function of the platform?

The general advice provided here might be helpful:
