[PATCH 0/3] use environment partitions in GPT

[Sascha Hauer <s.hauer@pengutronix.de>]

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.
