Glad to hear. Hopefully I will get more positive feedback.

I will fix that.

Questions for the maintainers:

1) I have some new variables for man_id, dev_id, cfi_version introduced by 
this patch (actually man_id is currently not used so could be removed). I 
can kept these local to the function for now or I can add them to the info 
structure along with ext_addr (to easily locate the Vendor Extended Query 
Structure in flash). What do you think?

In the minimum displaying man_id, dev_id, cfi_version when executing 
"flinfo" command could be useful for diagnostic purposes. We might need to 
use them to tweak the behavior of some other functionality in the future as 
well.

2) There are some outdated comments at the beginning of the cfi_flash.c. The 
modification history is not up to date and todo list stuff is mostly 
addressed over time. Since the actual history is already is the git, I 
propose to get rid of modification history and todo list from the comments.

Best regards,
