Remarks

NPA_Add_Option is used to collect all possible systems resource identifiers that might be passed as valid command line parameters to the driver. While this function can be used by CMDs for registering command line parameters, its primary purpose is to allow HAMs to collect parameters that are related to system resources for registration, such as the bus slot, interrupt, I/O ports, and memory decode options.
