7 Script to remove boards
10 rmboard.py <board_name>...
12 A single commit is created for each board removed.
14 Some boards may depend on files provided by another and this will cause
15 problems, generally the removal of files which should not be removed.
18 - Looking through the MAINTAINERS files which mention a board to find out
19 what files the board uses
20 - Looking through the Kconfig files which mention a board to find one that
21 needs to have material removed
23 Search for ## to update the commit message manually.
