As the document said, I tried added "#define DEBUG" in each file but it doesn't work. If I add "#define debug printf" then, of course debug() is printed.

Hello all,
I'm trying to boot from RAM using SPL only.
(Another scp processor loads the FIT image to the SDRAM before starting u-boot-spl is started)
Since the debugger doesn't work yet, I have to rely on prints to debug.
The printf works fine (I once asked about initializing serial port here, and later found serial_init is done in board_init_f ).
I tried to make debug(xxx) printed to serial port but couldn't figure out how to do it.
I tried
1. Adding #define DEBUG to the relevant source file
2. Giving DEBUG=1 in the make command (or CFLAGS=-DDEBUG)
But it doesn't work (of course I can change debug to printf to see it).
How can I make debug( ) macro output to the serial port?
Thank you!
Chan Kim
