If you are looking for timestamps before each logged message in the console, 
then _NO_ BOOTSTAGE will not add those. It does give a report later on (or 
when you explicitly execute 'bootstage report').

Did you read the README file? Did you check the configuration of other 
boards using the BOOTSTAGE? For example coreboot.h or sandbox.h?

All the best,
Rommel
