-/* Anomalies notes:
- *
- * 05000450 - MUSB driver is designed to transfer buffer of N*maxpacket size
- * in DMA mode 1 and leave rest data to the next transfer in DMA
- * mode 0.
- *
- * 05000463 - This anomaly doesn't affect this driver,Since it
- * never uses L1 or L2 memory as data destination.
- *
- * 05000464 - This anomaly doesn't affect this driver,Since it
- * never uses L1 or L2 memory as data source.
- *
- * 05000465 - Actually,the anomaly still can be seen when SCLK
- * is over 100 MHz,and there is no way to workaround
- * for bulk endpoints,because the wMaxPackSize of bulk
- * is less than or equal to 512,while the fifo size of
- * endpoint 5,6,7 is 1024,the double buffer mode is
- * enabled automatically when these endpoints are used
- * for bulk OUT.
- *
- * 05000466 - This anomaly doesn't affect this driver,Since it
- * never mixs concurrent DMA and core accesses to the
- * TX endpoint FIFOs.
- *
- * 05000467 - The workaround for this anomaly will introduce another
- * anomaly - 05000465.

+ * MUSB driver is designed to transfer buffer of N * maxpacket size
+ * in DMA mode 1 and leave rest data to the next transfer in DMA
+ * mode 0, so we never transmit a short packet in DMA mode 1.
