From 639448912ba17a9af9e759efbab37d36c6e29dea Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Thu, 17 Sep 2020 12:07:52 +0200 Subject: [PATCH] arm64: tegra: Initial Tegra234 VDK support The NVIDIA Tegra234 VDK is a simulation platform for the Orin SoC. It supports a subset of the peripherals that will be available in the final chip and serves as a bootstrapping platform.
