Re: [PATCH v4] arm64: zynqmp: Add support for Xilinx Kria SOM board

There are couple of revisions of SOMs (k26) and associated carrier cards
(kv260).
SOM itself has two major versions:
sm-k26 - SOM with EMMC
smk-k26 - SOM without EMMC used on starter kit with preprogrammed firmware
in QSPI.

SOMs are describing only devices available on the SOM or connections which
are described in specification (for example UART, fwuen).
