that's what I thought, too, but I wanted to give all information -
which obviously failed:

I am using a PEEDI (Hw:1.2, L:BDM v1.1 Fw:6.1.0) for debugging.

The funny thing is I can set breakpoints up to the relocation point:
(gdb) b board_init_f
Breakpoint 1 at 0x40020890: file board.c, line 244.
(gdb) c
Continuing.

Breakpoint 1, board_init_f (bootflag=0x0) at board.c:244
244             gd = (gd_t *) (CONFIG_SYS_INIT_RAM_ADDR + CONFIG_SYS_GBL_DATA_OFFSET);

Wolfgang
