When fsl,erratum-a011043 is set, adjust for erratum A011043: MDIO reads to internal PCS registers may result in having the MDIO_CFG[MDIO_RD_ER] bit set, even when there is no error and read data (MDIO_DATA[MDIO_DATA]) is correct. Software may get false read error when reading internal PCS registers through MDIO. As a workaround, all internal MDIO accesses should ignore the MDIO_CFG[MDIO_RD_ER] bit.

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.
