  12          Say Y here if your system has a dual role high speed USB
  13          controller based on the Mentor Graphics silicon IP.  Then
  14          configure options to match your silicon and the board
  15          it's being used with, including the USB peripheral role,
  16          or the USB host role, or both.

 112          Do not choose this unless DMA support for your SOC or board
 113          is unavailable (or unstable).  When DMA is enabled at compile time,
 114          you can still disable it at run time using the "use_dma=n" module
 115          parameter.
