TF-A supports reading input data from UART interfaces. This opens up
an attack vector for arbitrary data to be injected into TF-A, which is
not covered in the threat model right now.
Fill this gap by:
- Updating the data flow diagrams. Data may flow from the UART into
TF-A (and not only the other way around).
- Documenting the threats inherent to reading untrusted data from a
UART.
