In eDMA the events are directly mapped to a DMA channel (for example DMA event 14 can only be handled by DMA channel 14). If the memcpy is enabled on the eDMA, there is a possibility that the crossbar driver would assign DMA event number already allocated in eDMA for memcpy. Furthermore the eDMA can be shared with DSP in which case the crossbar driver should also avoid mapping xbar events to DSP used event numbers (or channels).
