|
The IXP4xx network processors have a CompactFlash interface that presents
|
|
a CompactFlash card to the system as a true IDE (parallel ATA) device. The
|
|
device is always connected to the expansion bus of the IXP4xx SoCs using one
|
|
or two chip select areas and address translating logic on the board. The
|
|
node must be placed inside a chip select node on the IXP4xx expansion bus.
