DWC2 peripherals can have TxFIFO sizes configured to any value between 16 and 32768. The value configured during synthesis is the maximum value the software can program. Designs that give full flexibility configure the TxFIFO sizes to value equal to total SPRAM size. Currently DWC2 driver does not have prior knowledge about the endpoints used within available configurations and has to come up with TxFIFO0 value up front. The original approach was to use MAX(16, max allowed). locations. Because DWC2 peripheral cannot have TxFIFO0 with size lower than 16 locations, always the max allowed was used. This logic prevented any IN endpoint other than EP0 on designs that have TxFIFO0 size set to total SPRAM size. Change the logic to MIN(2 * 16, max allowed) to have sufficient memory available on flexible designs and allow simultaneous operation if possible (i.e. when maximum TxFIFO0 size is at least 32).
