There are two drivers in the cs89x0 file, with the CONFIG_CS89x0_PLATFORM symbol deciding which one is getting built. This is somewhat confusing and makes it more likely ton configure a driver that works nowhere. Split up the Kconfig option into separate ISA and PLATFORM drivers, with the ISA symbol explicitly connecting to the static probing in drivers/net/Space.c The two drivers are still mutually incompatible at compile time, which could be lifted by splitting them into multiple files, but in practice this will make no difference. The platform driver can now be enabled for compile-testing on non-ARM machines. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: David S. Miller <davem@davemloft.net>

|
* 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.
