[PATCH v2 0/7] U-Boot environment data as a filesystem

Everyone:

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.

Feedback is welcome!

Changes since [v1]:

    - ubootvar changed to not rely on struct resource
    */mem_write/mem_read etc. and use a private pointer instead

    - ubootvar changed to handle the case of no valid environment data
      by allocation parition 0 as empty/new
      
    - Added documentation for ubootvarfs as well as ubootvar DT
      bindings

Thanks,
Andrey Smirnov
