If unsure, say N.config NR_ONCHIP_DMA_CHANNELS	depends on SH_DMA	int "Number of on-chip DMAC channels"	default "4"	help	  This allows you to specify the number of channels that the on-chip	  DMAC supports. This will be 4 for SH7750/SH7751 and 8 for the	  SH7750R/SH7751R.config NR_DMA_CHANNELS_BOOL	depends on SH_DMA	bool "Override default number of maximum DMA channels"	help	  This allows you to forcibly update the maximum number of supported	  DMA channels for a given board. If this is unset, this will default	  to the number of channels that the on-chip DMAC has.config NR_DMA_CHANNELS	int "Maximum number of DMA channels"	depends on SH_DMA && NR_DMA_CHANNELS_BOOL	default NR_ONCHIP_DMA_CHANNELS	help	  This allows you to specify the maximum number of DMA channels to	  support. Setting this to a higher value allows for cascading DMACs	  with additional channels.config DMA_PAGE_OPS	bool "Use DMAC for page copy/clear"	depends on SH_DMA && BROKEN	help	  Selecting this option will use a dual-address mode configured channel	  in the SH DMAC for copy_page()/clear_page(). Primarily a performance	  hack.config DMA_PAGE_OPS_CHANNEL	depends on DMA_PAGE_OPS	int "DMA channel for sh memory-manager page copy/clear"	default "3"	help	  This allows the specification of the dual address dma channel,	  in case channel 3 is unavailable. On the SH4, channels 1,2, and 3	  are dual-address capable.endmenu
