Should ARCH_EP93XX select > EP93XX_DMA to keep this, or should it be added to the ep93xx_defconfig? There are no users for the DMA in ep93xx_defconfig so I think that it shouldn't be selected by default. I was planning to change platform code to be conditionally compiled, like: arch/arm/mach-ep93xx/Makefile: +obj-$(CONFIG_EP93XX_DMA) += dma.o Any objections? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
