Then it claims this device supports CFI. I guess it is easier to get the values from sharp.c than from this datasheet :-(. [It seems like the chip has many "options", and it is up to user how it uses the chip.] Pavel -- Thanks, Sharp! - 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/
