  	bool "DMA Engine support"

  	depends on HAS_DMA

  	help

  	  DMA engines can do asynchronous data transfers without
  	  involving the host CPU.  Currently, this framework can be
  	  used to offload memory copies in the network stack and

  	  RAID operations in the MD driver.  This menu only presents
  	  DMA Device drivers supported by the configured arch, it may
  	  be empty in some cases.

  config DMADEVICES_DEBUG

          help
            This is an option for use by developers; most people should
            say N here.  This enables DMA engine core and driver debugging.
  
  config DMADEVICES_VDEBUG
          bool "DMA Engine verbose debugging"
          depends on DMADEVICES_DEBUG != n
          help
            This is an option for use by developers; most people should
            say N here.  This enables deeper (more verbose) debugging of
            the DMA engine core and drivers.
