From 7a4c31ee877a40053e39b80fe1d61c42b49f1078 Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Wed, 22 Sep 2021 09:07:32 +0200 Subject: 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). When SOM boots out of QSPI it uses limited number of peripherals defined by the specification and present in sm(k)-k26 dtses. Then a carrier card (CC) detection is happening and DT overlay is applied to brings new functionality. That's why DT overlays are used. The name is composed together with SOM name and CC name that's why DT overlays with these names are generated to make sure they can be used together.
