+v1.00			modify by simon 2001.9.5
+			change for kernel 2.4.x
+
+v1.1   11/09/2001	fix force mode bug
+
+v1.2   03/18/2003       Weilun Huang <weilun_huang@davicom.com.tw>:
+			Fixed phy reset.
+			Added tx/rx 32 bit mode.
+			Cleaned up for kernel merge.
+
+--------------------------------------
+
+       12/15/2003       Initial port to u-boot by
+       			Sascha Hauer <saschahauer@web.de>
+
+       06/03/2008	Remy Bohmer <linux@bohmer.net>
+			- Fixed the driver to work with DM9000A.
+			  (check on ISR receive status bit before reading the
+			  FIFO as described in DM9000 programming guide and
+			  application notes)
+			- Added autodetect of databus width.
+			- Made debug code compile again.
+			- Adapt eth_send such that it matches the DM9000*
+			  application notes. Needed to make it work properly
+			  for DM9000A.
+			- Adapted reset procedure to match DM9000 application
+			  notes (i.e. double reset)
+			- some minor code cleanups
+			These changes are tested with DM9000{A,EP,E} together
+			with a 200MHz Atmel AT91SAM9261 core
+
+TODO: external MII is not functional, only internal at the moment.
