IIRC some archs might return a tag instead of an address expected by readl/writel. I think you should either switch to ioread32/iowrite32 or to ioremap. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
