Subject: [PATCH v8 04/32] arm: qemu: Add a devicetree file for qemu_arm64 virt
Date: Thu, 16 Dec 2021 20:59:11 -0700	[thread overview]
Message-ID: <20211217035939.670884-5-sjg@chromium.org> (raw)
In-Reply-To: <20211217035939.670884-1-sjg@chromium.org>

This uses QEMU virt which creates its own devicetree.

Add an empty version of this file, so that we can at least build this
board when devicetrees are required.

Tested-by: Heinrich Schuchardt <heinrich.schuchardt@canaonical.com>
Signed-off-by: Simon Glass <sjg@chromium.org>
