Subject: [PATCH v8 11/32] arm: bcm7xxx: Add a devicetree file
Date: Thu, 16 Dec 2021 20:59:18 -0700	[thread overview]
Message-ID: <20211217035939.670884-12-sjg@chromium.org> (raw)
In-Reply-To: <20211217035939.670884-1-sjg@chromium.org>

Add an empty devicetree file for these boards. It seems to be possible to
obtain a real one from another bootloader called 'bolt' but I will leave
this to the maintainer.

Signed-off-by: Simon Glass <sjg@chromium.org>

Changes in v8:
- Mention that this is empty, rather than a dummy file
