sysupgrade.bin 结构：

┌────────────────┬──────────────┬──────────┐
34+
│ kernel (16MB) │ rootfs │ metadata │
35+
└────────────────┴──────────────┴──────────┘
36+
37+
写入到 /dev/mmcblk0p3 时：
38+
┌───────── 从这里开始写入
39+
↓
40+
┌──────────┬──────────┬────────────┬──────────────┐
41+
│ fastboot │ bootargs │ kernel │ rootfs │
42+

43+
│ 0-1MB │ 1-2MB │ 2MB-18MB │ 18MB-530MB │
44+
└──────────┴──────────┴────────────┴──────────────┘
45+
│←── 16MB ──→│←─ rootfs ──→│
46+
写入覆盖这两个分区
