# When calling avbtool make_vbmeta_image, it uses the `partitions`
# dictionary to include the options for --include_descriptors_from_image.
# The vbmeta image is different if the order of the
# --include_descriptors_from_image changes. As the images are generated
# parallelly and entries are added on completion of image creation,
# this `partitions` dict might be indeterministic as the order of
# completion of image creation cannot be predicted.
# To address this issue, add keys to the dict `partitions` with null values
# in the order they are listed in the variable `add_partition_calls`, and
# then the values are updated by `add_partition` keeping the order of the
# items. This ensures generated vbmeta.img is the same for the same input.
