The S25HL-T/S25HS-T family is the Infineon SEMPER Flash with Quad SPI. These Infineon chips support volatile version of configuration registers and it is recommended to update volatile registers in the field application due to a risk of the non-volatile registers corruption by power interrupt. Add support for volatile QE bit. For the single-die package parts (512Mb and 1Gb), only bottom 4KB and uniform sector sizes are supported. This is due to missing or incorrect entries in SMPT. Fixup for other sector sizes configurations will be followed up as needed. Tested on Xilinx Zynq-7000 FPGA 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.
