title: U-Boot environment variables
|
|
|
|
description: |
|
|
U-Boot uses environment variables to store device parameters and
|
|
configuration. They may be used for booting process, setup or keeping end user
|
|
info.
|
|
|
|
Data is stored using U-Boot specific formats (variant specific header and NUL
|
|
separated key-value pairs).
|
|
|
|
Environment data can be stored on various storage entities, e.g.:
|
|
1. Raw flash partition
|
|
2. UBI volume
|
|
|
|
This binding allows marking storage device (as containing env data) and
|
|
specifying used format.
|
|
|
|
Right now only flash partition case is covered but it may be extended to e.g.
|
|
UBI volumes in the future.
