partition-type : < partition > /* 分区类型 */
partition-size : < partition > /* 分区大小 */
unlocked /* 设备lock状态 */
off-mode-charge
battery-voltage
variant
battery-soc-ok
slot-count /* slot 数目 */
has-slot: < partition > /* 查看slot内是否有该分区名 */
current-slot /* 当前启动的slot */
slot-suffixes /* 当前设备具有的slot,打印出其name */
slot-successful: < _a | _b > /* 查看分区是否正确校验启动过 */
