Line 705 in ofw_standard.c is

	return ((void *)args.baseaddr);

args.baseaddr is a cell_t, which is defined in <machine/ofw_machdep.h>:

typedef	uint32_t	cell_t;

which I assume is correct for powerpc (32-bits), but probably not for
powerpc64.  Note that it is defined as uint64_t on sparc64 and sun4v,
and in sys/boot as unsigned long int, which is the correct size on both
32-bit and 64-bit machines (assuming I32LP64).
