Hi,
This patchset adds initial support for 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
You may also want to enable CONFIG_ARM_APPENDED_DTB and
CONFIG_ARM_ATAG_DTB_COMPAT if the bootloader doesn't support DT yet.
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.
v2:
Rebased against the latest Stephen Warren's linux-next_common
Add /cpus entry in DT
Add comment to initialize TSC only in secure mode.
