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

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