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.
