7 bool "SuperH on-chip DMA controller (DMAC) support"
8 depends on CPU_SH3 || CPU_SH4
12 config NR_ONCHIP_DMA_CHANNELS
14 int "Number of on-chip DMAC channels"
15 default "8" if CPU_SUBTYPE_SH7750R || CPU_SUBTYPE_SH7751R
16 default "12" if CPU_SUBTYPE_SH7780
19 This allows you to specify the number of channels that the on-chip
20 DMAC supports. This will be 4 for SH7750/SH7751 and 8 for the
23 config NR_DMA_CHANNELS_BOOL
25 bool "Override default number of maximum DMA channels"
27 This allows you to forcibly update the maximum number of supported
28 DMA channels for a given board. If this is unset, this will default
29 to the number of channels that the on-chip DMAC has.
31 config NR_DMA_CHANNELS
32 int "Maximum number of DMA channels"
33 depends on SH_DMA && NR_DMA_CHANNELS_BOOL
34 default NR_ONCHIP_DMA_CHANNELS
36 This allows you to specify the maximum number of DMA channels to
37 support. Setting this to a higher value allows for cascading DMACs
38 with additional channels.
41 bool "SH7760 DMABRG support"
42 depends on CPU_SUBTYPE_SH7760
44 The DMABRG does data transfers from main memory to Audio/USB units
46 Say Y if you want to use Audio/USB DMA on your SH7760 board.
