| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two kinds of dsaf device in hns, one is for service ports, contains crossbar in it, can work under different mode. Another is for debug port, only can work under "single-port" mode. The current code only declared a dsaf device for both service ports and debug ports.
