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