ETM architecture defines the system instructions for accessing via register accesses. Add basic support for accessing a given register via system instructions. We split the list of registers as : 1) Accessible only from memory mapped interface 2) Accessible from system register instructions. All registers are accessible via the memory-mapped interface. However, some registers are not accessible via the system instructions. This list is then used to further filter out the files we expose via sysfs.

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.
