there was a patch recently that fixed a bug in the context of partition
fixups and as a result repaired the state fixup as well for some setups:
http://lists.infradead.org/pipermail/barebox/2018-October/035091.html
Please check if it solves your problem. If not then please provide more
insight into your devicetrees (barebox & kernel) and post a little bit
more context of the state node as well as the eeprom and the aliases
nodes.
Best regards
Ulrich
