GSC FW is loaded by submitting a dedicated command via the GSC engine.
The memory area used for loading the FW is then re-purposed as local
memory for the GSC itself, so we use a separate allocation instead of
using the one where we keep the firmware stored for reload.
The GSC is not reset as part of GT reset, so we only need to load it on
first boot and S3/S4 exit.
v2: use REG_* for register fields definitions (Rodrigo), move to WQ
immediately
v3: mark worker function as static

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.
