We are trying to get away from hardcoding partitions outside the GPT in
the device tree and I think we are there.

A partition with the type UUID PARTITION_BAREBOX_ENVIRONMENT_GUID will be
used as environment partition automatically.

A partition with the type UUID BAREBOX_STATE_PARTITION_GUID will be used
as state partition provided the state node points to the device
containing this partition.

We also have a parted command to create/modify partitions and for
further convenience a createnv command which will create a barebox
environment partition in case you haven't built a full partition image
from a BSP.

It would be great if you could test this and eventually switch over to
it.
