avb2.0: implement AVB ops Implement AVB ops on top of existing mmc subsystem API. Currently there is a full implementation of such operations, defined by [1] AVB2.0 specification: .read_from_partition() - reads N bytes from a partition identified by a name. .write_to_partition() - Writes N bytes to a partition identified by a name. .validate_vbmeta_public_key() - checks if the given public ‘vbmeta’ partition is trusted. .get_unique_guid_for_partition() - Gets the GUID for a partition identified by a string name. As [1] specification recommends to use tamper-evident storage for storing rollback indexes and device state (LOCKED/UNLOCKED), currently are only stubs instead of full implementation for these ops: .read_rollback_index() - Gets the rollback index for a given index location .write_rollback_index() - Sets the rollback index to a given location .read_is_device_unlocked() - Gets where the device is unlocked [1] https://android.googlesource.com/platform/external/avb/+/master/README.md Signed-off-by: Igor Opaniuk <igor.opaniuk@linaro.org>
