Previously, the driver mapped the entire SPI address decoding region during probe. On systems with small flash or limited memory, this could lead to excessive memory usage or allocation failures. This patch changes the strategy to initially map a small address window for SPI flash device probing. After determining each chip select's flash size, the driver unmaps the temporary region and remaps only the required address window accordingly.

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.
