The requested_partitions[] array should contain only boot partitions. Usually it's only 'boot' partition, as can be seen in [1]. Also, seems like the requested_partitions[] are only used when there is no 'vbmeta' partition [2], which is not a regular use-case.
Make requested_partitions[] contain only 'boot' partition as it was supposed to be, and also make that array to be a local in do_avb_verify_part() function, as nobody else needs that.

Thanks for the patch.
Current snapshot of libavb in U-boot is a bit out-dated (~2 years) and before introducing patches that can leverage new features from the mainline libavb(taking into account that you're referring to Jul 30, 2019 patch 36d41d9223 ("Add AVB_SLOT_VERIFY_FLAGS_NO_VBMETA_PARTITION flag")) it makes sense to update libavb in U-boot first:
The best approach I see here (just to summarize what we've already discussed): 1. Update libavb to the latest stable version 2. Check if `avb verify` still behaves as expected on non-AB setups. 3. Introduce support of AB slots and different fixes like this one
Thanks
