Jaccon Bastiaansen e9460a9e81 CS89x0 : add platform driver support 
The CS89x0 ethernet controller is used on a number of evaluation
boards, such as the MX31ADS. The current driver has memory address and
IRQ settings for each board on which this controller is used. Driver
updates are therefore required to support other boards that also use
the CS89x0. To avoid these driver updates, a better mechanism
(platform driver support) is added to communicate the board dependent
settings to the driver.

/*
* INET An implementation of the TCP/IP protocol suite for the LINUX
* operating system. INET is implemented using the BSD Socket
* interface as the means of communication with the user level.
*
* Holds initial configuration information for devices.
*
* Version: @(#)Space.c 1.0.7 08/12/93
*
* Authors: Ross Biro
* Fred N. van Kempen, <waltje@uWalt.NL.Mugnet.ORG>
* Donald J. Becker, <becker@scyld.com>
*
* Changelog:
* Stephen Hemminger (09/2003)
* - get rid of pre-linked dev list, dynamic device allocation
* Paul Gortmaker (03/2002)
* - struct init cleanup, enable multiple ISA autoprobes.
* Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 09/1999
* - fix sbni: s/device/net_device/
* Paul Gortmaker (06/98):
* - sort probes in a sane way, make sure all (safe) probes
* get run once & failed autoprobes don't autoprobe again.
