The two external MDIO buses used to communicate with phy devices that are external to SOC are muxed in LX2160AQDS board. These buses can be routed to any one of the eight IO slots on LX2160AQDS board depending on value in fpga register 0x54. Additionally the external MDIO1 is used to communicate to the onboard RGMII phy devices. The mdio1 is controlled by bits 4-7 of fpga register and mdio2 is controlled by bits 4-7 of fpga register.

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.
