I plan to could do 'mount -t axfs /dev/mtdblock2 /mnt/axfs' and use the mtd to get the address to flash from map->cached or maybe mtd->point. Personally I think this is a clean approach to mounting this fs. Right now we do it like linear cramfs 'mount -t cramfs -o physaddr=0xDEADBEEF /dev/null /mnt/axfs' and then map flash ourselves with ioremap(). I'd like to enable a mode like this to in case you don't have MTD. But I prefer the former.

Haven't done any performance testing on squashfs. I did see some compression analysis that basically showed that squashfs did compress better but paid for that flash saving in extra RAM. - 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/
