[U-Boot-Users] IXP4XX NPE Support

[Michael Sprauve <mike_sprauve@yahoo.com>]

Hi Stefan,
Thanks for the file, the build works again, so now I
am moving to the next steps, it appears that the
software is not recognizing the NPE, so I would
imagine that there are some vars that need to be added
to the "include/configs/ixdp425.h" to make the port
available.
