* Update Intel IXP4xx support
- Add IXP4xx NPE ethernet MAC support - Add support for Intel IXDPG425 board - Add support for Prodrive PDNB3 board - Add IRQ support Patch by Stefan Roese, 23 May 2006 [This patch does not include cpu/ixp/npe/IxNpeMicrocode.c which still sufferes from licensing issues. Blame Intel.]
