> This patch uses gd->relocaddr variable to store uboot's relocated

>
> This patch moves CONFIG_AMIGAONEG3SE style copying of the address
> in board_init_f to just before relocation is actually done.

We can forgive a man for making a useful thing as long as he does not
admire it.  The only excuse  for making  a useless  thing is that one
admires it intensely.
