Hmm, can you try commenting out these 2 lines in arch/arm/cpu/armv7/sunxi/board.c :

#ifdef CONFIG_MACPWR
         gpio_request(CONFIG_MACPWR, "macpwr");
         gpio_direction_output(CONFIG_MACPWR, 1);
#endif

Around line 103 ? That is the only bit which has changed in
the SPL path due to this patch.

Hans
