Subject: [PATCH v2 02/10] ARM: dts: list the CPU nodes for Exynos5250
Date: Fri, 14 Jun 2013 19:32:44 +0530 [thread overview]
Message-ID: <1371218572-8993-3-git-send-email-chander.kashyap@linaro.org> (raw)
In-Reply-To: <1371218572-8993-1-git-send-email-chander.kashyap@linaro.org>
Instead of having to specify the number for CPUs in Exynos5250 in platsmp.c
file, let the number of CPUs be determined by having this information listed
in Exynos5250 device tree file.
