Date: Thu, 20 Dec 2012 11:43:58 +0200 Message-ID: <1355996654-6579-1-git-send-email-hdoyu@nvidia.com> X-Mailer: git-send-email 1.7.9.5 MIME-Version: 1.0 Content-Type: text/plain Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Hi, This patchset adds initial support for the NVIDIA's new Tegra 114 SoC (T114) based on the ARM Cortex-A15 MP. It has the minimal support to allow the kernel to boot up into shell console. This can be used as a basis for adding other device drivers for this SoC. Currently there are 2 evaluation boards available, "Dalmore" and "Pluto". This patchset is against Stephen Warren's linux-next_common branch: git://nv-tegra.nvidia.com/user/swarren/linux-2.6 linux-next_common For those who want to try: $ make ARCH=arm tegra_defconfig $ scripts/config -e ARCH_TEGRA_114_SOC -d DRM -d SUSPEND \ -d PM_RUNTIME -d CPU_FREQ -d CPU_IDLE $ make ARCH=arm menuconfig # if needed to configure more $ make ARCH=arm all -j9 Verified that this single image booted up with "Dalmore(T114)", "Pluto(T114)" and "Cardhu(T30)". For "Cardhu(T30)" with this single image, SPI driver doesn't seem to afford the above configuration , it hangs at boot-up. With SPI disabled, it's ok.
