SH_DMA_API

SuperH DMA API support

SH_DMA_API always enabled DMA API of used SuperH.
If you want to use DMA ENGINE, you must not enable this.
Please enable DMA_ENGINE and SH_DMAE.

NR_ONCHIP_DMA_CHANNELS

This allows you to specify the number of channels that the on-chip
DMAC supports. This will be 4 for SH7750/SH7751/Sh7750S/SH7091 and 8 for the
SH7750R/SH7751R/SH7760, 12 for the SH7723/SH7780/SH7785/SH7724, default is 6.

SH_DMABRG

SH7760 DMABRG support

The DMABRG does data transfers from main memory to Audio/USB units
of the SH7760.
Say Y if you want to use Audio/USB DMA on your SH7760 board.

PVR2_DMA

PowerVR 2 DMAC support

Selecting this will enable support for the PVR2 DMA controller.
As this chains off of the on-chip DMAC, that must also be
enabled by default.

This is primarily used by the pvr2fb framebuffer driver for
certain optimizations, but is not necessary for functionality.

If in doubt, say N.

G2_DMA

G2 Bus DMA support

This enables support for the DMA controller for the Dreamcast's
G2 bus. Drivers that want this will generally enable this on
their own.

If in doubt, say N.
