As my target board is PowerPC based (and therefore skipping relocation is not possible), I need help with my previously enumerated questions.
1) In section 10.4, Tips and Tricks, it says "To prevent GDB from jumping around in the code when trying to single step, i. e. when it seems as if the code is not executing line by line, you can recompile your code with the following additional compiler options: "-fno-schedule-insns -fno-schedule-insns"
In the u-boot developer world, what is the best practice for adding these compiler options? I see CFLAGS in config.mk and assume that is what needs to be modified. However, I need a HOWTODOITRIGHT
3) The function board_init_f() in board.c makes calls to debug(). I cannot determine how to enable debug() output. I saw one reference in the manual, but it gave no specifics.

Dear Wolfgang Denk,
Yes, it is true.
Currently only for ARMs and i386.
Best Regards,

- I am using a bdi3000. Is there no way to build u-boot so that it is
directly loaded to RAM by the debugger and does not relocate itself?
#define CONFIG_SKIP_RELOCATE_UBOOT
Note that this doesn't exist on ll architectures. For example on PowerPC, we will always relocate.
