The rest would be same since TSC initialization and dynamic core detections are still necessary/valid for Tegra as backup of /cpus DT failure. Or if you take this series as is first, I'll make a /cpus DT patchset agaist this series. > 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)".
