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. | |
