The CPU Core Complex or other masters within the MSS do not generate
AXI-Locked or exclusive transactions. The Ax_LOCK signal is not used, except for FIC to FIC
transfers.
- Any exclusive transactions generated by the FIC masters are treated as
normal transactions and generate an OKAY response.
- If exclusive access is generated on FICx with FICy as a destination,
for compliance the same exclusive access appears on FICy (the Ax_LOCK is asserted).
