Subject: [PATCH 0/9] ARM: Initial support for Tegra 114 SoC.

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.
