We have a region for reading the contents of the NVM flash as a snapshot. This region does not allow reading the Shadow RAM, as it always passes the FLASH_ONLY bit to the low level firmware interface. Add a separate shadow-ram region which will allow snapshot of the current contents of the Shadow RAM. This data is built from the NVM contents but is distinct as the device builds up the Shadow RAM during initialization, so being able to snapshot its contents can be useful when attempting to debug flash related issues. Fix the comment description of the nvm-flash region which incorrectly stated that it filled the shadow-ram region, and add a comment explaining that the nvm-flash region does not actually read the Shadow RAM.

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.
