about ufs Come on , The following features must be supported ：
（1）LU The number of is determined by bMaxNumberLU decision , Every UFS Most support 2 individual Boot LU.
（2） There is one. RPMB LU,RPMB LU The interior can also be divided into 4 Small RPMB Area (RPMB region 0 - RPMB region 3).

For each LU It has the following common characteristics ：
（1） Address spaces are independent of each other , The addresses are from 0 Start
（2）LU Size can be matched
