We have specified a GUID for GPTs to be used as barebox environment partition, but so far we haven't made any use of that. This series changes that. We now start using environment partitions when we find them, provided the board code hasn't specified any other partition. This likely doesn't change much for existing boards because most of them actually have an environment partition specified. For new boards however it becomes feasible to not register a partition explicitly. Something that has hold me back from doing this earlier was that barebox was not able to create an environment partition itself, so barebox couldn't persist the environment on an unpartitioned device. Now with parted support this has changed, so I think it's worth it to give it a try now.
