+ *  Function:	Device driver for the ethernet EMAC3 macro on the 405GP.
+ *
+ *  Author:	Mark Wisner
+ *
+ *  Change Activity-
+ *
+ *  Date	Description of Change					    BY
+ *  ---------	---------------------					    ---
+ *  05-May-99	Created							    MKW
+ *  27-Jun-99	Clean up						    JWB
+ *  16-Jul-99	Added MAL error recovery and better IP packet handling	    MKW
+ *  29-Jul-99	Added Full duplex support				    MKW
+ *  06-Aug-99	Changed names for Mal CR reg				    MKW
+ *  23-Aug-99	Turned off SYE when running at 10Mbs			    MKW
+ *  24-Aug-99	Marked descriptor empty after call_xlc			    MKW
+ *  07-Sep-99	Set MAL RX buffer size reg to ENET_MAX_MTU_ALIGNED / 16	    MCG
+ *		to avoid chaining maximum sized packets. Push starting
+ *		RX descriptor address up to the next cache line boundary.
+ *  16-Jan-00	Added support for booting with IP of 0x0		    MKW
+ *  15-Mar-00	Updated enetInit() to enable broadcast addresses in the
+ *		EMAC_RXM register.					    JWB
+ *  12-Mar-01	anne-sophie.harnois@nextream.fr
+ *		 - Variables are compatible with those already defined in
+ *		  include/net.h
+ *		- Receive buffer descriptor ring is used to send buffers
+ *		  to the user
+ *		- Info print about send/received/handled packet number if
+ *		  INFO_405_ENET is set
+ *  17-Apr-01	stefan.roese@esd-electronics.com
+ *		- MAL reset in "eth_halt" included
+ *		- Enet speed and duplex output now in one line
+ *  08-May-01	stefan.roese@esd-electronics.com
+ *		- MAL error handling added (eth_init called again)
+ *  13-Nov-01	stefan.roese@esd-electronics.com
+ *		- Set IST bit in EMAC_M1 reg upon 100MBit or full duplex
+ *  04-Jan-02	stefan.roese@esd-electronics.com
+ *		- Wait for PHY auto negotiation to complete added
+ *  06-Feb-02	stefan.roese@esd-electronics.com
+ *		- Bug fixed in waiting for auto negotiation to complete
+ *  26-Feb-02	stefan.roese@esd-electronics.com
+ *		- rx and tx buffer descriptors now allocated (no fixed address
+ *		  used anymore)
+ *  17-Jun-02	stefan.roese@esd-electronics.com
+ *		- MAL error debug printf 'M' removed (rx de interrupt may
+ *		  occur upon many incoming packets with only 4 rx buffers).
+ *-----------------------------------------------------------------------------*
+ *  17-Nov-03	travis.sawyer@sandburst.com
+ *		- ported from 405gp_enet.c to utilized upto 4 EMAC ports
+ *		  in the 440GX.	 This port should work with the 440GP
+ *		  (2 EMACs) also
+ *  15-Aug-05	sr@denx.de
+ *		- merged 405gp_enet.c and 440gx_enet.c to generic 4xx_enet.c
+		  now handling all 4xx cpu's.
