| * Common rules for -r/-w/-v syntax parsing: |
| * - If no filename is specified at all, quit. |
| * - If no filename is specified for -r/-w/-v, but files are specified |
| * for -i, then the number of file arguments for -i options must be |
| * equal to the total number of -i options. |
| * |
| * Rules for reading: |
| * - If files are specified for -i args but not -r, do partial reads for |
| * each -i arg, creating a new file for each region. Each -i option |
| * must specify a filename. |
| * - If filenames are specified for -r and -i args, then: |
| * - Do partial read for each -i arg, creating a new file for |
| * each region where a filename is provided (-i region:filename). |
| * - Create a ROM-sized file with partially filled content. For each |
| * -i arg, fill the corresponding offset with content from ROM. |
| * |
| * Rules for writing and verifying: |
| * - If files are specified for both -w/-v and -i args, -i files take |
| * priority. (Note: We determined this was the most useful syntax for |
| * chromium.org's flashrom after some discussion. Upstream may wish |
| * to quit in this case due to ambiguity). |
| * See: http://crbug.com/263495. |
| * - If file is specified for -w/-v and no files are specified with -i |
| * args, then the file is to be used for writing/verifying the entire |
| * ROM. |
| * - If files are specified for -i args but not -w, do partial writes |
| * for each -i arg. Likewise for -v and -i args. All -i args must |
| * supply a filename. Any omission is considered ambiguous. |
| * - Regions with a filename associated must not overlap. This is also |
| * considered ambiguous. Note: This is checked later since it requires |
| * processing the layout/fmap first. |
