+Subject: [PATCH] Enable UART mux setting before SOL activation via SSH
+
+Switching UART routing when starting obmc-service introduces garbled
+character printing out on physical host serial output and it's
+inevitable so this commit moves the routing logic into host console
+connection flow in SSH SOL to avoid the issue until SOL is actually
+activated.
+
+Tested: SOL activation is working fine via SSH
