36 * 16 MiB NOR flash. The struct mtd_partition is not in the same order as the
37 * partitions on the device because we want to keep compatability with
38 * the QNAP firmware.
39 * Layout as used by QNAP:
40 * 0x00000000-0x00080000 : "U-Boot"
41 * 0x00200000-0x00400000 : "Kernel"
42 * 0x00400000-0x00d00000 : "RootFS"
43 * 0x00d00000-0x01000000 : "RootFS2"
44 * 0x00080000-0x000c0000 : "U-Boot Config"
45 * 0x000c0000-0x00200000 : "NAS Config"
46 *
47 * We'll use "RootFS1" instead of "RootFS" to stay compatible with the layout
48 * used by the QNAP TS-109/TS-209.
