13
  The IXP4xx network processors have a CompactFlash interface that presents

14
  a CompactFlash card to the system as a true IDE (parallel ATA) device. The

15
  device is always connected to the expansion bus of the IXP4xx SoCs using one

16
  or two chip select areas and address translating logic on the board. The

17
  node must be placed inside a chip select node on the IXP4xx expansion bus.
