In case of coldfire/5272 a fixed phy is used, which so far is created by platform code, using fixed_phy_add(). This function has a number of problems, therefore create a potentially needed fixed phy here, using fixed_phy_register_100fd. Note 1: This includes a small functional change, as coldfire/5272 created a fixed phy in half-duplex mode. Likely this was by mistake, because the fec MAC is 100FD-capable, and connection is to a switch. Note 2: Usage of phy_find_next() makes use of the fact that dev_id can only be 0 or 1. Due to lack of hardware, this is compile-tested only.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
