My first reaction is this is ugly.

I suggest
	gmac4_addr = ioremap(CPHYSADDR(nlm_mmio_base(NETLOGIC_IO_GMAC_4_OFFSET)),
			     0xfff);

or using a temporary or a #define for
	CPHYSADDR(nlm_mmio_base(NETLOGIC_IO_GMAC_4_OFFSET))

or add a new define like:

#define MMIO_CPHYSADDR(addr) (CPHYSADDR(nlm_mmio_base(addr)))

and change all the netlogic uses of CPHYSADDR so this one
could be

	gmac4_addr = ioremap(MMIO_CPHYSADDR(NETLOGIC_IO_GMAC_4_OFFSET), 0xfff);

etc...
