With the introduction of the Icicle Kit using the production MPFS250T device, it's necessary to distinguish it from the engineering sample (-es) variant. Engineering samples cannot write to flash from the MSS, as noted in the PolarFire SoC FPGA ES errata. Add specific compatibles for the Icicle Kit with Production device (MPFS250T) and Icicle Kit with Engineering Sample (MPFS250T_ES). The icicle kit reference designs in the v2025.07 release include the Mi-V IHC IP v2, used to send/receive data between clusters when using Asymmetric Multiprocessing (AMP) mode. In reference design releases prior to v2025.07, the MI-V IHC subsystem was included as a proof of concept in the design prior to becoming an IP available in the Libero catalog. Among other improvements, the new Mi-V IHC IP v2 includes some changes to the register map. For this reason, make use of a new reference design compatible to denote that v2025.07 reference design releases are not backwards compatible.

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.
