| H A D | pio.h | diff 234579 Sun Apr 22 19:06:55 MDT 2012 nwhitehorn Replace eieio; sync for creating bus-space memory barriers with sync. sync performs a strict superset of the functions of eieio, so using both is redundant. While here, expand bus barriers to all bus_space operations, since many drivers do not correctly use bus_space_barrier(). In principle, we can also replace sync just with eieio, for a significant performance increase, but it remains to be seen whether any poorly-written drivers currently depend on the side effects of sync to properly function.
