Change in ...flashrom[master]: [RFC] cli_classic: Add `--mode (read|write|verify|erase)` parameter
by Nico Huber (Code Review) 13 May '21

13 May '21

Nico Huber has uploaded this change for review. ( https://review.coreboot.org/c/flashrom/+/30979 Change subject: [RFC] cli_classic: Add `--mode (read|write|verify|erase)` parameter ...................................................................... [RFC] cli_classic: Add `--mode (read|write|verify|erase)` parameter In case the user only wants to specify files for specific layout regions, we need a way to set the operation without specifying a file. Instead of making the <filename> argument optional, we can add a new syntax for this particular purpose. This way, we avoid complex command line parsing and can do more sanity checks and provide better error messages. TODO: Update manpage in case this gets accepted.
