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.
