The patch updates the booting-without-of.txt-file.
There is a description for the case
if mdio data and clock pins are on different processor ports.
It extends the "[PATCH v3] using mii-bitbang on different processor ports".

The patch makes possible to have mdio and mdc pins on different physical ports
also for CONFIG_PPC_CPM_NEW_BINDING.
To setup it in the device tree:
reg = <10d40 14 10d60 14>; // mdc: 0x10d40, mdio: 0x10d60
or
reg = <10d40 14>; // mdc and mdio have the same offset 10d40
The approach was taken from o

The spacing is still wrong.
- iounmap(bitbang->dir);
+ if ( bitbang->mdio.dir != bitbang->mdc.dir)
+ iounmap(bitbang->mdio.dir);
+ iounmap(bitbang->mdc.dir);
And here.
