Do we really need the NAND driver to be able to use more than one layout? Either we have hardware ECC which determines the layout, or the NAND driver implements software ECC and gets to choose. Can't the filesystem just deal with the ECC layout used by the NAND driver, as determined by the underlying hardware? -- dwmw2
