Our controller is expecting ECAM size to be programmed by software. By programming "NWL_ECAM_VALUE_DEFAULT 12" controller can access up to 16MB ECAM region which is used to detect 16 buses, so by updating "NWL_ECAM_VALUE_DEFAULT" to 16 so that controller can access up to 256MB ECAM region to detect 256 buses.
