    sys/dev/uart         uart_dev_ns8250.c 
  Log:
  Partial MFC of rev 1.22 (the other bits were already MFC'd by marcel).
  Additionally, remove the probe for the high 4 bits of IER being 0 and don't
  assume we can always read/write 0 to/from those bits.
  
  This is needed to get uart(4) to work on Xscale PXA255 and IXP425.
