The u-boot companion command line tool 'fw_setenv' emits verbose output
during a set operation of the form:
Unlocking flash...
Done
Erasing old environment...
Done
Writing environment to /dev/mtd4...
Done
Locking ...
Done
While this is nice for debugging and troubleshooting, it is a bit verbose in
a production environment. I propose two alternatives for suppressing this
output:
1) Compile-time: Change 'printf' to 'debug' in which case the above
diagnostics will only be output when the tool is built with 'DEBUG'
asserted.
2) Run-time: Change the implementation such that the invocation usage of
'fw_setenv' is:
Usage: fw_setenv [ -q ] name [ value ... ]
I'd favor (2); however, I welcome strong opinions one way or another before
I submit a patch.
Regards,
Grant
