Subject: [PATCH 28/40] ARM: ux500: Remove UART support when booting without Device Tree
Date: Fri, 23 Aug 2013 13:23:28 +0100	[thread overview]
Message-ID: <1377260620-18829-29-git-send-email-lee.jones@linaro.org> (raw)
In-Reply-To: <1377260620-18829-1-git-send-email-lee.jones@linaro.org>

It's time to remove all ATAG support from ux500 and rely solely on
Device Tree booting. This patch is part of that endeavour.
