Subject: [PATCH v8 09/32] arm: octeontx: Add an empty devicetree file
Date: Thu, 16 Dec 2021 20:59:16 -0700	[thread overview]
Message-ID: <20211217035939.670884-10-sjg@chromium.org> (raw)
In-Reply-To: <20211217035939.670884-1-sjg@chromium.org>

Add an empty file to prevent build errors when building with
CONFIG_OF_SEPARATE enabled.

Unfortunately there are no build instructions in the U-Boot tree to enable
a real file to be created.

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

(no changes since v7)

Changes in v7:
- Use 'empty' instead of 'fake'
