[U-Boot] u-boot newbie - question about the 'debug( )' function ...

[Jonathan Barrow]

In many of the sources, such as "board.c",  I notice calls to
'debug()'.  The syntax looks similar to printf(),   e.g.:  debug
("Stack Pointer at: %08lx\n", addr_sp);

Is this output sent to the BDM, such as bdi2000?  or Ethernet?  posted
to memory?

Also, is debug() related to the setting in 'config.mk' :

     DBGFLAGS= -g # DDEBUG

I can't seem to locate where it lives, so uncertain how it works.

Thank You,
