I vaguely remember doingn some research in this area a few years ago looking a report on linuxppc-dev about this and the kernel's unaligned access was dependant on the device being given a mtd point function which means the device is directly accessible in the cpus address space. I don't remember much beyond that and don't have time to dig. I am just an observer with respect to linux mtd. > > Thanks, > Michal Hope this helps your research, milton -- 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/
