This script attempts to create a git commit which removes a single board. It is quite fallible and everything it does needs checking. But it can help speed up the process. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Chris Packham <judge.packham@gmail.com>

Script to remove boards
|
|
|
|
Usage:
|
|
rmboard.py <board_name>...
|
|
|
|
A single commit is created for each board removed.
|
|
|
|
Some boards may depend on files provided by another and this will cause
|
|
problems, generally the removal of files which should not be removed.
|
|
|
|
This script works by:
|
|
- Looking through the MAINTAINERS files which mention a board to find out
|
|
what files the board uses
|
|
- Looking through the Kconfig files which mention a board to find one that
|
|
needs to have material removed
|
|
|
|
Search for ## to update the commit message manually.
