Hi developers,
i made a patch for an PXA270-evalboard with DM9000
ethernet contoller. The Interrupt can be high- or low-
active dependant of the wiring of the MDC-(57)pin.
Because of this hardware dependency you shoud be able
to configure this behaviour in "struct resource dm9000_resources[]"
Please comment an review my patch which is attached here
Thanksalot
Jürgen Schindele
