Subject: [PATCH] Documentation: Update env sources documentation
Date: Tue, 18 May 2021 23:01:34 -0700 [thread overview]
Message-ID: <20210519060134.2976676-1-tpiepho@gmail.com> (raw)
Add CONFIG_DEFAULT_ENVIRONMENT_PATH to the list in the proper place.
Update the board env to follow the new pattern for naming and note that,
unlike the other directories, one must add code to get this directory in
the environment.

- defaultenv/defaultenv-2-reboot-mode -> overlay for reboot modes

Note that not all of the above directories will necessarily be
included in your default environment, it depends on your barebox
