Subject: [PATCH v2 0/5] Icicle Kit with prod device and Discovery Kit support

Hi all,

With the introduction of the Icicle Kit with the production device
(MPFS250T) to the market, it's necessary to distinguish it from the
engineering sample (-es) variant. This is because engineering samples
cannot write to flash from the MSS, as noted in the PolarFire SoC
FPGA ES errata.

This series adds a common board DTSI for the Icicle Kit, containing
hardware shared by both the engineering sample and production
versions, as well as a DTS for each Icicle Kit variant.

The last two patches add support for the PolarFire SoC Discovery Kit
board.

Changes since v1:
 - fix order of properties in mailbox nodes
 - drop redundant status property from ddrc_cache nodes
 - fix lowecase hex in reserved memory regions

Thanks,
Valentina
