fs_mg: allow getting VBMeta Digest from device-tree
fs_mgr gets androidboot.vbmeta.{size, hash_alg, digest} from kernel
cmdline to assure the integrity of all vbmeta structs. This CL Allows
fs_mgr to get those parameters from device tree because they're only
consumed by userland instead of kernel.
https://android.googlesource.com/platform/external/avb/+/master#The-VBMeta-Digest
Bootloader could construct a device tree overlay at run time then merge
it into main device tree. e.g.,
firmware {
android {
vbmeta.size = "5245";
vbmeta.hash_alg = "sha256";
vbmeta.digest = "0c51233ca3ecaa...63c6d912e79b709";
};
};
Bug: 80168311
Test: boot a device using AVB
