This patch removes some ft_board_setup() functions from some 4xx boards. This can be done since we now have a default weak implementation for this in cpu/ppc4xx/fdt.c. Only board in need for a different/custom implementation like canyonlands need their own version. Signed-off-by: Stefan Roese <sr@denx.de>
