/* Anomalies notes:
 *
 *  05000450 - USB DMA Mode 1 Short Packet Data Corruption:
 *             MUSB driver is designed to transfer buffer of N * maxpacket size
 *             in DMA mode 1 and leave the rest of the data to the next
 *             transfer in DMA mode 0, so we never transmit a short packet in
 *             DMA mode 1.
 *
 *  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 - The anomaly can be seen when SCLK is over 100 MHz, and there is
 *             no way to workaround for bulk endpoints.  Since 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 mixes
 *             concurrent DMA and core accesses to the TX endpoint FIFOs.
 *
 *  05000467 - The workaround for this anomaly will introduce another
 *             anomaly - 05000465.

/* The Mentor USB DMA engine on BF52x (silicon v0.0 and v0.1) seems to be
 * unstable in host mode.  This may be caused by Anomaly 05000380.  After
 * digging out the root cause, we will change this number accordingly.
 * So, need to either use silicon v0.2+ or disable DMA mode in MUSB.
