This 12 can be integrated in chips such as the Atmel AT32ap7000. 13 14config DW_DMAC_BIG_ENDIAN_IO 15 bool "Use big endian I/O register access" 16 default y if AVR32 17 depends on DW_DMAC 18 help 19 Say yes here to use big endian I/O access when reading and writing 20 to the DMA controller registers. This is needed on some platforms, 21 like the Atmel AVR32 architecture. 22 23 If unsure, use the default setting. 24
