Both are less than optimal. The first clashes with the need to use a GPT partition for the state and the second doesn't allow relating the UUID with an actual device for the case where e.g. both an SD-Card and an eMMC are flashed with the same image. This series fixes that by: - Supporting definition of fixed partitions that are identical to GPT/MBR partitions. - Alternatively, support pointing barebox-state backend at a GPT-partitioned device and the partition with the barebox-state Type GUID will be taken.
