Brian is adding the read-retry feature. I think the data randomization should be done by the hardware. If we do it by software, it costs lot of the cpu cycles. > Kernel also does not support synchronous NAND. The synchronous NAND should be supported by the nand controller driver, not the kernel. thanks Huang Shijie -- 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/
