Dear Mark,

Is this really how you called GDB?
GNU gdb 5.1.1
Where did you get this GDB from?
This GDB was configured as "--host=i386-redhat-linux --target=ppc-linux". (gdb) bdi 0xff000100 in ?? () (gdb) ram add symbol table from file "u-boot" at .text_addr = 0x7fc0000 (gdb) info address rtx Symbol "rtx" is static storage at address 0xff0312d8. (gdb)
In the unlikely case you are not aware rtx is defined in cpu/mpc8260/ether_fcc.c as ...
The same works fine here:

And just to verify without relocation:
