To implement the devlink device flash functionality, the driver needs to access both the device memory and the internal flash memory. The flash memory is accessed using a device-specific program (called the flash utility). This flash utility must be downloaded by the driver into the device memory and then executed by the device CPU. Once running, the flash utility provides a flash API to access the flash memory itself. During this operation, the normal functionality provided by the standard firmware is not available. Therefore, the driver must ensure that DPLL callbacks and monitoring functions are not executed during the flash operation. Add all necessary functions for downloading the utility to device memory, entering and exiting flash mode, and performing flash operations.

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 reStructuredText 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.
