This series of patches introduces support of Android Verified Boot 2.0, which provides integrity checking of Android partitions on MMC.
It integrates libavb/libavb_ab into the U-boot, provides implementation of AvbOps, subset of `avb` commands to run verification chain (and for debugging purposes), and it enables AVB2.0 verification on AM57xx HS SoC by default.
Currently, there is still no support for verification of A/B boot slots and no rollback protection (for storing rollback indexes there are plans to use eMMC RPMB)
Libavb/libavb_ab will be deviated from AOSP upstream in the future, that's why minimal amount of changes were introduced into the lib sources, so checkpatch may fail.
For additional details check [1] AVB 2.0 README and doc/README.avb2, which is a part of this patchset.
