Subject: [PATCH v2 3/5] ARM: plat-samsung: use Kconfig choice for debug UART selection
Date: Tue, 23 Aug 2011 22:30:40 +0100	[thread overview]
Message-ID: <1314135042-19908-4-git-send-email-will.deacon@arm.com> (raw)
In-Reply-To: <1314135042-19908-1-git-send-email-will.deacon@arm.com>

Now that the DEBUG_LL UART can be selected by a Kconfig choice, convert
the Samsung UART selection to use a set of bools rather than an int.

Acked-by: Nicolas Pitre <nicolas.pitre@linaro.org>
