Well, but probably it is better to remove both lines. In the rest of
u-boot, DEBUG is neither set or unset - you see only #ifdef DEBUG or
#ifndef DEBUG. You have found the examples how we should not do...

If you want to remember how to set the debug output, it should be enough
to add a comments with "to enable the debugging, define DEBUG before
common.h" or something like that. I vote to remove only the two lines...

Best regards,
Stefano
