When the EEPROM MAC is read by way of ADDRH, it can return all 0s the first time. Subsequent reads succeed. This is fully reproduceable on the Phytec PCM049 SOM. Re-read the ADDRH when this behaviour is observed, in an attempt to correctly apply the EEPROM MAC address.

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.
