Hello,

Attached is a patch that allows use of memory-mapped devices other than CPU GPIO on boards when bit-banging MDIO. The config option MDIO_PORT is now the differentiator as to whether the memory mapped device is on a CPU port or not.

CHANGELOG:

* Changed conditional inclusion of ioport variable to boards that define the MDIO_PORT macro.

regards, Ben
