From 4a37134f5f739a2cfed6426d296f7755044d2d28 Mon Sep 17 00:00:00 2001 From: Andreas Sandberg Date: Wed, 6 Jun 2018 18:28:43 +0100 Subject: system-arm: Split the VExpress_GEM5_V1 base dts With the introduction of the new DPU model, we need different variations of the VExpress_GEM5_V1 platform. This splits the platform dtsi file into a separate file for the base platform and the HDLCD-based platform. This matches the hierarchy in RealView.py.
