Subject: [PATCH v2 0/7] U-Boot environment data as a filesystem
Date: Mon, 3 Jun 2019 22:19:56 -0700 [thread overview]
Message-ID: <20190604052003.3189-1-andrew.smirnov@gmail.com> (raw)
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
