The netc-blk-ctrl driver is used to configure Integrated Endpoint Register Block (IERB) and Privileged Register Block (PRB) of NETC. For i.MX platforms, it is also used to configure the NETCMIX block. The IERB contains registers that are used for pre-boot initialization, debug, and non-customer configuration. The PRB controls global reset and global error handling for NETC. The NETCMIX block is mainly used to set MII protocol and PCS protocol of the links, it also contains settings for some other functions. Note the IERB configuration registers can only be written after being unlocked by PRB, otherwise, all write operations are inhibited. A warm reset is performed when the IERB is unlocked, and it results in an FLR to all NETC devices. Therefore, all NETC device drivers must be probed or initialized after the warm reset is finished.

README
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.
