So we get the relocation address of U-Boot: 0x8FF67000
And in gdb we can load the symbol-file:
Program received signal SIGSTOP, Stopped (signal).
0x8ff90554 in ?? ()
(gdb) add-symbol-file u-boot 0x8ff67000
add symbol table from file "u-boot" at
.text_addr = 0x8ff67000

Simple test, set breakpoint @ do_version:
(gdb) b do_bdinfo
Breakpoint 1 at 0x8ff6a680: file cmd_bdinfo.c, line 373.
(gdb) c
Continuing.
In U-Boot type version:
OMAP3 Tricorder # bdinfo
And in gdb the breakpoint is hit:
