Internal address mode (3- or 4-byte) affects to the address length in Read Any Reg op. Read Any Reg op is used in SMPT parse and other setup functions. Current driver assumes that address mode is factory default but users can change it via volatile and non-volatile registers. Current address mode can be checked by CFR2V[7] but Read Any Reg op is needed to read CFR2V (chicken-and-egg). Introduce a way to determine current address mode by comparing status register 1 values read by different address length.

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.
