This 16 can be integrated in chips such as the Atmel AT32ap7000. 17 18config DW_DMAC_PCI 19 tristate "Synopsys DesignWare AHB DMA PCI driver" 20 depends on PCI 21 select DW_DMAC_CORE 22 help 23 Support the Synopsys DesignWare AHB DMA controller on the 24 platfroms that enumerate it as a PCI device. For example, 25 Intel Medfield has integrated this GPDMA controller. 26 27config DW_DMAC_BIG_ENDIAN_IO 28 bool "Use big endian I/O register access" 29 default y if AVR32 30 depends on DW_DMAC_CORE 31 help 32 Say yes here to use big endian I/O access when reading and writing 33 to the DMA controller registers. This is needed on some platforms, 34 like the Atmel AVR32 architecture. 35 36 If unsure, use the default setting. 37
