> -Intel's IXP2000 family of NPUs (IXP2400, IXP2800, IXP2850) is designed
> -for high-performance network applications such high-availability
> -telecom systems. In addition to an XScale core, it contains up to 8
> -"MicroEngines" that run special code, several high-end networking
> -interfaces (UTOPIA, SPI, etc), a PCI host bridge, one serial port,
> -flash interface, and some other odds and ends. For more information, see:
> -
> -http://developer.intel.com
> -
> -2. Linux Support
> -
> -Linux currently supports the following features on the IXP2000 NPUs:
> -
> -- On-chip serial
> -- PCI
> -- Flash (MTD/JFFS2)
> -- I2C through GPIO
> -- Timers (watchdog, OS)
> -
> -That is about all we can support under Linux ATM b/c the core networking
> -components of the chip are accessed via Intel's closed source SDK.
> -Please contact Intel directly on issues with using those. There is
> -also a mailing list run by some folks at Princeton University that might
> -be of help: https://lists.cs.princeton.edu/mailman/listinfo/ixp2xxx

> -MAILING LISTS REGARDING THE INTEL SDK.

> -4. Usage Notes
> -
> -- The IXP2000 platforms usually have rather complex PCI bus topologies
> - with large memory space requirements. In addition, b/c of the way the
> - Intel SDK is designed, devices are enumerated in a very specific
> - way. B/c of this this, we use "pci=firmware" option in the kernel
> - command line so that we do not re-enumerate the bus.
> -
> -- IXDP2x01 systems have variable clock tick rates that we cannot determine
> - via HW registers. The "ixdp2x01_clk=XXX" cmd line options allow you
> - to pass the clock rate to the board port.
> -
> -5. Thanks
