This adds support for the following 4GiB chips: GD5F4GQ4RCYIG 1.8V GD5F4GQ4UCYIG 3.3V The datasheet can be found here: https://www.novitronic.ch/sixcms/media.php/2/DS-00173-GD5F4GQ4xCxIG-Rev1.574695.pdf The GD5F4GQ4UCYIGT (3.3V) version is used on the Imagination Technologies Creator Ci40 (Marduk), the 1.8V version was not tested. This device only works in single SPI mode and not in dual or quad mode for me on this board.

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.
