Subject: [U-Boot] [PATCH v2 04/18] dm: serial: Don't support CONFIG_CONS_INDEX with device tree
Date: Tue, 12 May 2015 14:55:05 -0600	[thread overview]
Message-ID: <1431464119-21574-5-git-send-email-sjg@chromium.org> (raw)
In-Reply-To: <1431464119-21574-1-git-send-email-sjg@chromium.org>

This feature should be deprecated for new boards, and significantly adds
to SPL code size. Drop it. Instead, we can use stdout-path in the /chosen
node.
