Subject: [PATCH V2 1/6] ARM: tegra: add Tegra124 SoC support
Date: Tue, 8 Oct 2013 12:50:03 +0800 [thread overview]
Message-ID: <1381207808-14734-2-git-send-email-josephl@nvidia.com> (raw)
In-Reply-To: <1381207808-14734-1-git-send-email-josephl-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>
Add Tegra124 SoC support that base on CortexA15MP Core. And enable the
SMP function that can re-use the same procedure with Tegra114.
