It's pretty trivial stuff.  I don't have a patch for you, but go into
start.S and look for the relocate_code symbol.  All the stuff between
there and clear_bss is strictly relocation code.  I just exported the
clear_bss symbol and called it from board_init_f!  (but I had to fix
up some of the calling parameters first.  *HUGE* hack, but it worked.
:)  I don't do this any more though.

(hint: add #define DEBUG above the includes in board.c)

You need to load the symbol table at an offset.  I think you use the
add-symbol-file command.  The details are in the u-boot documentation
somewhere.
