14 * pio_phys_read_mmr - read an MMR
15 * pio_phys_write_mmr - write an MMR
16 * pio_atomic_phys_write_mmrs - atomically write 1 or 2 MMRs with psr.ic=0
17 * Second MMR will be skipped if address is NULL
19 * Addresses passed to these routines should be uncached physical addresses
20 * ie., 0x80000....
