Notes

A system-setting ("systemstartup!skip_psc_wait") and the output from pm:bm GetBootMode is used to determine a value passed to a func. When the setting is set to non-zero, the passed value is 2, otherwise the passed value is BootMode == Maintenance. This value is eventually written into global state.

The funcs which create threads "nn.notification.PresenterStateManagement" and "nn.notification.PresenterMain" will only create the threads when pm:bm GetBootMode output is Normal, otherwise these funcs just return.

prepro SetOperationMode is only used when pm:bm GetBootMode output is not Maintenance.
