Add PCI interface driver for Prestera Switch ASICs family devices, which
provides:
- Firmware loading mechanism
- Requests & events handling to/from the firmware
- Access to the firmware on the bus level
The firmware has to be loaded each time the device is reset. The driver
is loading it from:
/lib/firmware/mrvl/prestera/mvsw_prestera_fw-v{MAJOR}.{MINOR}.img
The full firmware image version is located within the internal header
and consists of 3 numbers - MAJOR.MINOR.PATCH. Additionally, driver has
hard-coded minimum supported firmware version which it can work with:
MAJOR - reflects the support on ABI level between driver and loaded
firmware, this number should be the same for driver and loaded
firmware.
MINOR - this is the minimum supported version between driver and the
firmware.
PATCH - indicates only fixes, firmware ABI is not changed.
Firmware image file name contains only MAJOR and MINOR numbers to make
driver be compatible with any PATCH version.

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.
