[PATCH 0/7] U-Boot environment data as a filesystem

This series adds code needed to expose U-Boot environemnt variable
data partition as a regular filesystem in Barebox. It currently only
supports the use-case where environment is stored on SD/MMC device,
since that is the only use-case I have access to for testing, however
adding support for other cases should be relatively
straightforward. The series is currently lacking documentation for
Barebox specific DT bindings it introduces, however an example of
usage can be seen in

ARM: rdu2: Add U-Boot environment partitions
ARM: rdu1: Add U-Boot environment partition

I'll add the appropriate documentation in v2 once all of the details
are hashed out.

Feedback is welcome!
