This makes OpenWrt build an Ext2+Ext4 partitioned image for the D-Link DNS-313 with two blank partitions, a boot partition on /dev/sda3 and a rootfs partition on /dev/sda4. This uses the methods already used in apm821xx including the tricks to convert the generated Ext2 filesystem partition to version 1 so that the firmware bootloader will properly recognize it. We patch a bit around the build files to make sure we get the rootfs size set and that genext2fs is properly built. Tested on the D-Link DNS-313.
