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

	  Texas Instruments families using this IP include DaVinci
	  (35x, 644x ...), OMAP 243x, OMAP 3, and TUSB 6010.

	  Analog Devices parts using this IP include Blackfin BF54x,
	  BF525 and BF527.

	  If you do not know what this is, please say N.

	  To compile this driver as a module, choose M here; the
	  module will be called "musb-hdrc".

	  All data is copied between memory and FIFO by the CPU.
	  DMA controllers are ignored.

	  Do not choose this unless DMA support for your SOC or board

	  you can still disable it at run time using the "use_dma=n" module
	  parameter.
