At present binman returns success when told to handle missing/faked blobs or missing bintools. This is confusing since in fact the resulting image cannot work.
Use exit code 103 to signal this problem, with a -W option to convert it to a warning.
Rename the flag to --ignore-missing since it controls bintools also.
Add documentation about exit codes while we are here.
Signed-off-by: Simon Glass sjg@chromium.org ---
Changes in v5: - Add a note that -W requires -M - Update ftest use of -W to avoid confusion - Update exit-status docs to mention -W also - Rename flag to --ignore-missing - Update commit message - Correct help for -M flag
