   :name: MCTP Host Sample

   Create an MCTP host over UART.

Overview
********
Sets up an MCTP node that sends a request on a UART targeting a particular MCTP
endpoint id with the message "hello". Expects and waits for a response to this
"hello" message containing "world".

Requirements
************
A board and SoC that provide access to a UART and a driver that implements the
UART async API.

Wiring
******
The UART pins should be wired to a board which will run the MCTP endpoint
sample such that this board's UART tx pin connects to the endpoint board's rx
pin, and this board's UART rx pin connects to the endpoint board's tx pin. The
boards' grounds should also be wired together.

Optionally a logic analyzer can be wired up and listening to the UART to inspect
the data flowing.
