# Create new control files for checklist:
#
#     1. Remove any selection for CREATE_BOARD_CHECKLIST
#     2. Remove any selection for MAKE_CHECKLIST_PUBLIC
#     3. make
#     4. nm build/cbfs/fallback/<stage>.debug > <stage>_symbols.txt
#     6. sed 's/^...........//' <stage>_symbols.txt > <stage>_complete.dat
#     7. grep -F " W " <stage>_symbols.txt | sed 's/^...........//' \
#             > <stage>_optional.dat
#     8. Edit <stage>_complete.dat to remove any symbols that are not
#        desired in the report
#     9. Edit <stage>_optional.dat to remove any symbols that are
#        required to be implemented
#
# Create a board checklist:
#
#     1. select CREATE_BOARD_CHECKLIST
#     2. Optionally: select MAKE_CHECKLIST_PUBLIC
#     3. Specify CONFIG_CHECKLIST_DATA_FILE_LOCATION
#     4. make
#
# Build Errors:
#     * No checklist built - verify CREATE_BOARD_CHECKLIST is selected in
#           board Kconfig file.  Do a make clean
#     * <stage>_complete.dat not found - verify that
#           CONFIG_CHECKLIST_DATA_FILE_LOCATION points to the directory
#           containing the checklist data files.  Build the checklist
#           data files if necessary.
#     * Segmentation fault - most likely caused by $(NM_$(class)) not being
#           set.
