flashrom

With -i option, user can specify the regions they want to read.
flashrom reads whole flash and shows warnings for read-protected areas, even if those areas were not requested by -i

Example is with log attached, the command line is

flashrom -p internal -w <filename> --fmap -i EC -i COREBOOT -N >flashrom.log 2>&1

regions requested are EC and COREBOOT, in the logs there are 100+ warnings about "read_flash: cannot read inside Management Engine region" - but the user has not asked for ME region

The question is, should we show warnings for areas which are outside of what user requested?

Other notes:

• warnings are not blocking, but there can be a lot of them
• the option skip_unreadable_regions is not available from command line, but even if it would be available, this option impacts the reading from the whole flash regardless of what was requested by -i

This was raised from user experience of MrChromebox-flashrom, however this aspect seems the same for upstream too
