Now that we are using absolute paths we can remove some of the sys.path mangling that appears in the tools. We only need to add the path to 'tools/' so that everything can find modules relative to that directory. The special paths for finding pylibfdt remain. Signed-off-by: Simon Glass <sjg@chromium.org>

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.
