Modification from Emmanuel Raguet <raguet@crf.canon.fr> to merge the

dec21140 drivers from the i386/pc386 and powerpc/mcp750 (all Motorola
PowerPC boards) and move the network driver to libchip.  This driver
should work on all PCI based uses of this chip.

+This TULIP driver can be used on BSPs that support PCI bus.
+
+It can handle any DEC21140 based Ethernet controller. 
+  
+It works on big or little endian target.
+
+It has been tested with powerpc/mcp750 BSP (OnBoard Ethernet
+controller) and i386/pc386 BSP (D-Link DFE-500TX Ethernet board).
