# # DMA engine configuration for dw # config DW_DMAC tristate "Synopsys DesignWare AHB DMA support" depends on GENERIC_HARDIRQS select DMA_ENGINE default y if CPU_AT32AP7000 help Support the Synopsys DesignWare AHB DMA controller. This can be integrated in chips such as the Atmel AT32ap7000. config DW_DMAC_BIG_ENDIAN_IO bool "Use big endian I/O register access" default y if AVR32 depends on DW_DMAC help Say yes here to use big endian I/O access when reading and writing to the DMA controller registers. This is needed on some platforms, like the Atmel AVR32 architecture. If unsure, use the default setting.
