The patman directory has a number of modules which are used by other tools in U-Boot. This makes it hard to package the tools using pypi since the common files must be copied along with the tool that uses them. To address this, move these files into a new u_boot_pylib library. This can be packaged separately and listed as a dependency of each tool. 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.
