I applied this patch and tested on BCM47081 based device. I still got bgmac working which surely uses DMA. There is only 1 ARM wireless SoC using bcma (BCM47198) but its WiFi core isn't supported by b43.
Any tips what else to test? SPI core/driver doesn't use DMA. Maybe NAND core does, but we don't use it.
