Currently there is a device tree entry called "local-mac-address" which can be filled by the bootloader or manually set.This is useful when the user does not want to use the MAC address programmed into the SoC. Currently, the davinci_emac reads the MAC from the DT, copies it from pdata->mac_addr to priv->mac_addr, then blindly overwrites it by reading from registers in the SoC, and falls back to a random MAC if it's still not valid. This completely ignores any MAC address in the device tree. In order to use the local-mac-address, check to see if the contents of priv->mac_addr are valid before falling back to reading from the SoC when the MAC address is not valid.

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 Restructured Text 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.
