system分区大小修改：0x00400000@0x000e8800(system)

0x00400000：空间大小---修改这里

0x000e8800：空间地址

例如：0x00400000

2b0000（十六进制）转化为十进制，x 512变为字节 ，除于1024 ，然后在除于1024 ，得到最终的兆字节大小：1440mb

转化公式：

1.2b0000(十六进制)转化为(十进制)为：2949120

2.2949120 x 512字节 = 1509949440

3.1509949440 / 1024 = 1474560 KB

4.1474560 / 1024 = 1440 MB

注意：后面的空间地址=前面的空间大小 + 前面的地址大小，即：

0x00400000@0x000e8800(system),0x00008000@0x004e8800(metadata)

0x00400000 + 0x000e8800 = 0x004e8800
