Because all of these bugs in omap driver, I wonder how many people really use the mainline version. Also if you use a nand that need 4-bit ECC, you need a better ecc than hamming. You can use the bch code ( http://article.gmane.org/gmane.linux.drivers.mtd/37864/match=omap ) Matthieu PS : why omap driver use in omap_dev_ready GPMC*IRQ_STATUS instead of GPMC_STATUS. PS2 : ecc hamming look strange. Weird isEccFF code. Doesn't seem to handle bit flip in ecc. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
