modification history
--------------------
01f,16apr02,dat  Update for T2.2 release
01e,01aug00,rcs  Added DEC_USR_MII_10MB | DEC_USR_MII_HD | DEC_USR_MII_100MB 
                 | DEC_USR_MII_FD | DEC_USR_MII_BUS_MON macros to load string.
01d,31jul00,rcs  Added MII_PHY_AUTO in sysDec21x40UpdateLoadStr() to allow 
                 auto-negotiation.
01c,10jul00,dmw  Added DEC_USR_MII to force miiLib to use PHY address 8.
01b,28may99,rhk  changed names to dec21x40, changed dec2114xSromWordRead to
		 dec21140SromWordRead.  Removed motorola21143SromFix code.
01a,29apr99,rhk  Initial file checkin, from MVME2400 version.

.SH DESCRIPTION

This file contains the board-specific routines for the Motorola MV2100 with
on-board Digital Semiconductor 21140 Ethernet adapter and the Motorola
MV2100 with the Digital Semiconductor 21143 Ethernet adapter. This file is 
required to update the END load string that the END driver utilizes for 
initial configuration.

* This routine is to be called from sysHwInit() before the END initialization
* takes place, but after the network adapter under consideration has been
* configured by a mechanism such as PCI autoconfig. This routine will scan
* for the ethernet device via a call to the "sysLib.c" routine 
* sysDynEnetFind().  If the enternet device is found, the device's 
* configuration space is read, and the END load string is composed from this 
* information. The endDevTbl entry is then updated with a pointer to the 
* updated load string, which resides in statically allocated data local to 
* this module.
*
* Note that this routine assumes that the entry for the END device is the
* first entry in the in the END device table (endDevTbl[]).
