Description
经分析，并客户也反馈：
由于cmn协议的master对接口，不支持AXI4-Lite协议，并且像PCIE等设备误发出burstlen超过1个的时候，IMSIC会发出多个response，导致总线挂死行为，对于集成或功能上，都不灵活，建议将访问接口改为AXI4，以便更灵活处理。

Research direction
Start by locating the IMSIC access interface and the current AXI4-Lite connection to the cmn master. Review how burst lengths and responses are handled, then verify that the interface accepts AXI4 transactions, including bursts longer than one, without multiple responses causing the bus to hang.
