[Detail] Because Android P impose so many restrictions, it is difficult for meta mode or factory mode to format partitions. A new design is adopted as follows: 1. Meta mode or factory mode write all 0 to first 4KB of target partition. 2. When entering kernel booting, the partition mount process in the original init flow find that XXX partition is wiped and automatically format XXX partition. In step-1 described above, selinux rules shall be added for meta_tst or factory. In step-2 described above, selinux rules shall be added for mke2fs.
