默认关闭verity,无需手动执行OEM解锁和使用命令adb disable-verity
path: /external/avb/avbtool
将default=0改为default=2
sub_parser.add_argument('--flags',
help='VBMeta flags',
type=parse_number,
default=2)
# edited by peng default=0 to default=2将root所需文件直接放入源码，无需手动push
path: /out/target/product/evk_8mm/system/bin/install-recovery.sh
path: /out/target/product/evk_8mm/system/xbin/su
path: /out/target/product/evk_8mm/system/xbin/daemonsu
path: /out/target/product/evk_8mm/system/xbin/supolicy
path: /out/target/product/evk_8mm/system/lib64/libsupol.so
不编译su文件，防止编译后覆盖上述步骤2中的su文件
path: /system/extras/su/Android.mk
屏蔽如下代码：
