Subject: [PATCH 2/4] ARM: dts: imx6ul-kontron: Simplify devicetree structure
Date:   Tue,  9 Aug 2022 17:25:29 +0200
Message-Id: <20220809152534.292034-3-frieder@fris.de>

From: Frieder Schrempf <frieder.schrempf@kontron.de>

There is no need in differentiating between the different SoM versions
that only differ in memory size, etc. It's much cleaner to simplify
the devicetrees and let them be more generic.

If necessary the bootloader will update the devicetree dynamically
to contain the correct size of the memory.
