After some unsuccessful attempts to use sysrq over console, figured out that port->has_sysrq should likely be enabled, as per other architectures, this when CONFIG_SERIAL_MCF_CONSOLE is also enabled. Tested some magic sysrq commands (h, p, t, b), they works now properly. Commands works inside 5 secs after BREAK is sent, as expected.

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.
