Subject: [PATCH] arm: rpi: Device tree modifications for U-Boot
Date: Tue, 11 Aug 2015 08:25:53 -0600	[thread overview]
Message-ID: <1439303153-12171-1-git-send-email-sjg@chromium.org> (raw)

This updates the device tree from the kernel version to something suitable
for U-Boot:

- Add stdout-path alias for console
- Mark the /soc node to be available pre-relocation so that the early
serial console works (we need the 'ranges' property to be available)

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