Miquel Raynal b93f410b8b SPI NOR changes for 6.11 
Notable changes:
 
 - Drop support for Xilinx S3AN flashes. These flashes are for the very
   old Xilinx Spartan 3 FPGAs and they need some awkward code in the core
   to support. Drop support for these flashes, along with the special
   handling we needed for them in the core like non-power-of-2 page size
   handling and the .setup() callback.
 
 - Fix regression for old w25q128 flashes without SFDP tables. Commit
   83e824a4a5 ("mtd: spi-nor: Correct flags for Winbond w25q128")
   dropped support for such devices under the assumption that they aren't
   being used anymore. Users have now surfaced [0] so fix the regression
   by supporting both kind of devices.
 
 - Core cleanups including removal of SPI_NOR_NO_FR flag and
   simplification of spi_nor_get_flash_info().

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.
