AVB 2.0 spec. revision 1.1 introduces support for named persistent values that must be tamper evident and allows AVB to store arbitrary key-value pairs [1]. Introduce implementation of two additional AVB operations read_persistent_value()/write_persistent_value() for retrieving/storing named persistent values. Correspondent pull request in the OP-TEE OS project repo [2].
