microdroid: use a single vbmeta for all partitions Since we don't need to update partitions separately, a single vbmeta is enough for all partitions. Bug: 193504286 Test: atest MicrodroidHostTestCases Change-Id: I4f0e84dc0132c8f3ff9262e11bfc68eaf7863169

Mount system and vendor over dm-verity This CL fixes a series of mistakes which let the system and the vendor partition be mounted without dm-verity. * avb=vbmeta and avb=vbmeta_system flags are added to fstab so that the partitions are mounted over dm-verity * uboot script is modified to append avb_bootargs into bootargs so that avb parameters like the root hash, etc. are passed to the kernel via cmdline * The boot partition is no longer a chained partition. Its hashtree is included in vbmeta.img directly. This is firstly because we don't have a need to update the kernel independently from other partitions. And secondly, boot as a chained partition requires us to create /dev/block/by-name/boot during the first stage init, which require additional-but-useless entry in fstab. * Name of the logical partitions in super.img is changed to system_a and vendor_a from system and vendor, respectively. Bug: 198303625 Test: boot microdroid. `ls /dev/block/mapper` shows ``` drwxr-xr-x 3 root root 160 2021-09-01 03:10 . drwxr-xr-x 5 root root 1180 2021-09-01 03:10 .. drwxr-xr-x 2 root root 140 2021-09-01 03:10 by-uuid lrwxrwxrwx 1 root root 15 2021-09-01 03:10 microdroid-apk -> /dev/block/dm-4 lrwxrwxrwx 1 root root 15 2021-09-01 03:10 system-verity -> /dev/block/dm-2 lrwxrwxrwx 1 root root 15 2021-09-01 03:10 system_a -> /dev/block/dm-0 lrwxrwxrwx 1 root root 15 2021-09-01 03:10 vendor-verity -> /dev/block/dm-3 lrwxrwxrwx 1 root root 15 2021-09-01 03:10 vendor_a -> /dev/block/dm-1 ``` Change-Id: I6b485d841d9bd774ab964fd9ae7d2e0a15795b14
