[U-Boot-Users] [DNX#2006092742000013] [PATCH] Clean up dependency in bit-banged MDIO

[DENX Support System]

Hello list,

inside the automatic U-Boot patch tracking system a new ticket
[DNX#2006092742000013] was created:

<snip>
> 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.
