Modification from Emmanuel Raguet <raguet@…> 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.

5This TULIP driver can be used on BSPs that support PCI bus.
6
7It can handle any DEC21140 based Ethernet controller.
8 
9It works on big or little endian target.
10
11It has been tested with powerpc/mcp750 BSP (OnBoard Ethernet
12controller) and i386/pc386 BSP (D-Link DFE-500TX Ethernet board).
