Add two RSU environment variables: 1. rsu_log_level the variable is unsigned integer and its default value is RSU_DEBUG (7), which only show log with RSU_INFO,RSU_WARNING and RSU_ERR.
To enable all logs (RSU_ERR, RSU_WARNING, RSU_INFO and RSU_DEBUG), you need set log level to 8 or above via “setenv rsu_log_level 8”.
To disable all logs, you need set log level to 3 or below.
2. rsu_protected_slot by default there is no protected RSU slot, you need run "setenv rsu_protected_slot <slot_num>” to set a slot protected, and “setenv rsu_protected_slot <a space>” to unset a protected slot.
