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.
