Update libavb to commit 5fbb42a189aa in AOSP/master, because new version has support for super partition [1], which we need for implementing Android dynamic partitions. All changes from previous patches for libavb in U-Boot are accounted for in this commit: - commitecc6f6bea6("libavb: Handle wrong hashtree_error_mode in avb_append_options()") - commit897a1d947e("libavb: Update SPDX tag style") - commitd8f9d2af96("avb2.0: add Android Verified Boot 2.0 library") Tested on X15: ## Android Verified Boot 2.0 version 1.1.0 read_is_device_unlocked not supported yet read_rollback_index not supported yet read_is_device_unlocked not supported yet Verification passed successfully AVB verification OK. Unit test passes: $ ./test/py/test.py --bd sandbox --build -k test_avb test/py/tests/test_android/test_avb.py ss..s.
